including the Many Spelling Variations, such as, STROUP, STROUPE, STRAUBY, STRAUP, 
This project utilizes Y-chromosome DNA testing as a tool for genealogical research on the Germanic surnames STRAUB, TRAUB, STROOP, STRUB, and STRAUBE, and their numerous spelling variations, the most common of which in the United States are STROUP and TROUP.  The project is based at FamilyTreeDNA, but people tested elsewhere are welcome to join by sharing results and lineages, either unofficially or by officially transferring

Human gender is genetically determined by a pair of chromosomes that are, by convention, designated XX (for females) and XY (for males).  Only males have the Y-chromosome, and because the male Y-chromosome is handed down intact from father to son through the generations (except for rare mutations), Y-DNA testing can identify common ancestors on the direct male line.  Y-DNA testing is an extremely powerful tool for proving pedigrees and for breaking past brick walls where paper genealogy has failed to go.

If you are researching any of these surnames or their variations, please consider having a male family member submit a sample to the project.  The more participants we have, the more we will learn about our origins!  This invitation extends to African-American STRAUB/etc. families whose patrilineal ancestor either was genetically STRAUB/etc. or had adopted the surname of their STRAUB/etc. owner in the antebellum South if you don't know which is the case, then a DNA test is one way to find out.

And if you are new to genetic testing for genealogical purposes, you are encouraged to read the project FAQs and these articles:

DNA Test Results and Member Lineages

Haplogroup R1b is by far the most common haplogroup subclade in western Europe and I1 is the next most common, so it is not surprising that these two subclades are the ones most represented among test subjects.  Haplogroup E is a distant third.

Haplogroup E

Haplogroup E1b1b has a high frequency in some of the oldest populations in Europe (e.g., the Welsh).

E-1b1b-1 = E-M35.1

One of our project members is a descendant of Antonius STRAUB, of the German-speaking STRAUBs of Glogowatz, Austro-Hungary [now Romania]. 

Haplogroup I1

Haplogroup I1 is the most common form of Haplogroup I.  It is sometimes called the "Viking" haplogroup because of its concentration in northwestern Europe and Scandinavia (others consider only R1a to be the "true" Viking haplogroup, see below). 

I1 = I-M253 AngloSaxon-9a Cluster

This individual is a descendant of Jacob TRAUB / TROUP of Armstrong Co., PA.

I1 = I-M253 AngloSaxon-gen2 Cluster

This individual's ancestor was an adopted STROUP, so he is not genetically matching anyone in the project or, as it happens, anyone else in the FTDNA, Ysearch, or SMGF databases.

I1d = I-L22 Norse-Dansk Cluster

Norse is the most common I1 cluster in Sweden and Finland and the next most common in Norway and Denmark; the Norse-Dansk cluster is more common in Denmark.  We have two matching individuals in this group, each of whom was an unexpected result.  Their haplotype is uncommon: at  37 markers, they match no one else, except each other.

One individual is a purported descendant of John STRAUB, Sr. of Beaver Twp., Union [now Snyder] Co., PA, but he does not match the other purported descendant of John, who turns out to be a match with descendants of Johann Pieter STRAUB, the 1733 immigrant (I1-AS5, above).  As the other descendant has an essentially unassailable paper connection to John Sr., it appears this individual, who descends from Jonathan Francis STRAUB, is the one with the bad connection, especially in light of his connection to the next member.  Or is his paper connection correct, meaning this is yet another NPE?

His matching member is a TROUPE who descends from John Peter TRAUB / TROUP, also of Union [now Snyder] Co., PA, at the level of 37/37. 

I1 = I-M253 AngloSaxon-5 Cluster

Several members of this family have undergone deep SNP testing with the result that they are officially I-M253*.  One family member has taken the WTY test and found a new SNP:  L592.  This SNP has, so far, turned out to be "private" to the family, so it will not be forming a new subclade on the haplotree, at least not until other start showing up with it.  There are clusters of Haplogroup I1 defined by STR haplotypes and, based on them, this family is an uncommon cluster known as AngloSaxon-5 (AS5). 

Of the members who belong to this cluster, most are paper descendants of Martin STRAUB (1616-1676) of Gemmingen and Grossgartach, Heilbronn, Wuerttemberg.  Of these, one is still living in Germany, a descendant of Martin's grandson, Antonius STRAUB, while the others are living in the U.S., presumed descendants of Antonius's brother, Johann Pieter STRAUB, 1733 immigrant to Philadelphia.  The rest are Americans with paper trails that fall short of reaching Johann Peter, but have DNA test results indicating they are genetically closely related to the other descendants in this family.

Johann Pieter is the second earliest known STRAUB immigrant to the United States and has the most descendants of any single STRAUB immigrant to the United States (at least based on my research to date).  Results of these subjects match their modal haplotype at the level of 64/67 or better, one as high as 136/136, despite being nine to twelve generations from their common ancestor.  Other than their close matches with each other, their haplotypes are unique at 25 or more makers.

Among the descendants of Johann Pieter, DNA results support the allegation that John Peter STROUP of Wythe Co., VA, is a descendant of Johann Pieter I.  Interestingly, two other paper descendants of John Peter have been tested, and each has a different NPE in his lineage (see the listings below under NEUHAUS and R-1b1a-2a1a-1b4b).

Two unanticipated connections revealed by this testing are a descendant of John STRAUB of Beaver Twp., Union [now Snyder] Co., PA, and a descendant of John STRAUB, miller of Berks (now Schuylkill) Co., PA.

DNA results also confirm that an individual who acquired the surname BARNES from his foster father really is a descendant of Johann Pieter, as indicated in his paper genealogy.

Among this group, matching the descendants of Johann Pieter at the 64/67 to 67/67 level, are paper descendants of Jacob STROUP I (1724-1804) of Lincoln [now Gaston] Co., NC,  previously thought by many to be a grandson of Mathias STROOP, the 1687 emigrant from Westphalia to MD.  This startling DNA test result resurrects and supports the assertion by early researchers that this Jacob is the missing son, Johann Jacob, who accompanied Johann Pieter on the 1733 crossing.  In other words, Jacob STROUP I is not a grandson of Mathias STROOP.  Jacob I had an enormous number of descendants, so this result affects many living STROUPs and STROUPEs, mostly in the southern United States.  Also proven by DNA is that Jacob STROUP II (1771-1846), alleged grandson of Jacob I, is not genetically related to him (see Haplogroup J2 below).  A fourth individual, a descendant of Elisha STROUP (c1811-1893), has no paper connection to Jacob I, but is presumed to be descended from him because he was married in Lincoln Co., NC, before eventually settling in Georgia. 

The most unexpected individuals in this group are two non-STROUPs who apparently have NPE's, "non-paternal events" (i.e., a hidden adoption or illicit paternity) in their patrilineal lines.  [See this page for a further discussion of NPEs and their resolution.] 

One of the NPEs has a paper descent from Silas BELEW of Jefferson Co., MO; he has a 67/67 match with the modal haplotype of this STROUP family.  For decades, the BELEW family was in close contact with the STROUPs of Jefferson County, all of whom are believed to descend from sons of Adam STROUP, son of Jacob STROUP I, who moved to Jefferson County in the 1820s.

The other NPE is an individual with a paper descent from William Waitsel CRUMP of Caldwell and Gaston Cos., NC, illegitimate son of Rebecca CRUMP and Waightstill PRESTWOOD.  The location of the NPE in his line has not been determined, and it will require the testing of some selected cousins to determine in which generation it occurred.  There is no doubt, however, that he really is a STROUP because he matches the modal haplotype for this family at 66/67. Given his location in Gaston Co., NC, he is presumed to be a descendant of Jacob I.

These Haplogroup I1-AS5 STRAUBs and STROUPs have the distinction of being cousins of President Barack OBAMA through his mother, Stanley Ann (DUNHAM) OBAMA, a descendant of Johann Pieter STRAUB I

Haplogroup I2

Of our ten Haplogroup I2 members, nine were tested at FTDNA, while one was tested at SMGF.  Five are a form of I2a and five are a form of I2b.

I2a = I-P37.2

Johannes STRAUB (1682/3-) is the earliest known STRAUB immigrant to the United States to New York in 1710.  Most of his descendants converted to STROPE, some to STROUP.  One of his confirmed STROPE descendants has been tested, along with a STROUP from New York who has traced his ancestry to Jefferson Co., NY, but not connected to Johannes.  They are a tight, 65/67, match. 

I2a2 = I-M423 Dinaric-S Cluster

The two descendants of Jacob STROUP, who was born in PA and settled in Grant Co., IN, were expected to match, and they did.  What was unexpected was their match to a descendant of (Adam?) Michael STROUP of Maryland, whose sons settled in Highland Co., OH, and greatly proliferated there.  Their haplotype is uncommon, with just a handful of matches at 12 markers and no full matches at 25 markers.  Their haplotype is a variety known as "Dinaric" because these populations are believed to have refuged in the region of the Dinaric Alps in southeastern Europe during the last glacial maximum. One of them has been deep SNP tested confirming that they are Haplogroup I2a2 (M423+).

I2b1 = I-M223 Continental-2b Cluster

This individual is a descendant of Moses STROOP (1839-1887) of PA, then Chattanooga, TN.  He is not only unique in the project, as of this date (4 Jul 2015), he has no matches with anyone at any level in the FTDNA database.

I2b1a = I-M284 Isles/Sc Cluster

This individual is the one tested at SMGF.  He has no full or even near matches with anyone in the project or in any of the major online databases.  His pedigree at SMGF shows him to be a descendant of George STROUP of NY, whom we know as a descendant of Johannes STRAUB, the 1710 immigrant to NY and the earliest known STRAUB immigrant to the United States.  Most descendants converted to spelling STROPE, but some to STROUP.  The SMGF database gives no possible way to contact test subjects; so, if you are the test subject and are reading this page, please contact me (I'm willing to subsidize 50% of the cost of a conversion kit to join this project here at FTDNA).

I2b1c = I-P78 (deduced) Continental-3a Cluster

The I2b1c subclade of Haplogroup I is found thinly thoughout Europe, but is concentrated in central and northern Germany, the Netherlands, and Denmark.  The Continental Cluster is, as the name implies, concentrated in continental Europe, as opposed to the Brithis Isles or Scandinavia.  This individual descends from Henry STRAUB of Northumberland Co., PA, whose immigrant ancestor has yet to be identified.  His backbone SNP test proves he is Hg I2b1 (M223+); he is deduced to be I-P78. 

I2b2 = I-L38 (deduced) L38-A Cluster

The immigrant ancestor of these two Pennsylvania Deutsch STRAUBs is not known, nor do we have a paper connection between them.  One is a descendent of Theobald / Dewaldt STRAUB of Carbon Co., PA, whose early descendants are concentrated in that county and neighboring Northampton County.  The other is the Peter STRAUB / STROUP who lived in Perry Co., PA, and was formerly believed to descend from Johann Pieter STRAUB I.  Update:  they are now matched by a descendant of Friedrich Wilhelm STRAUB, immigrant to St. Louis, MO, in 1839, whose origin is in Burkhards, Hesse, Germany.

 Haplogroup J2
J-2a4h = J-L24 (deduced)

These three individuals are paper descendants of Jacob STROUP II (1771-1846), who was supposedly a grandson of Jacob STROUP I (1724-1804), but DNA evidence refutes this connection (see I1-AS5 above).  These three match no other STRAUB / STROUP yet tested, so as it stands, the parents of Jacob II are unknown.  These J2 STROUPs do match an individual surnamed BIDDLE (at the level of 35/37), so the search is on for an explanation, the most likely being that Jacob II, as the eldest paper son of Adam STROUP, was probably Adam's wife's son from a prior marriage.

J-2a4h-2 = J-L25

This individual descends from Mary STROUP (1845/6-1922) of Lincoln/Gaston Co., NC.  There was no expectation that he would match with STROUP, and he doesn't, nor does he, so far, match with anyone else.

Haplogroup R1a1
R-1a1 = R-M198

Two members with matching DNA are descendants of Andreas STRAUB, of Östringen, Baden, four of whose sons immigrated to the United States, three settling in Michigan and the fourth in Indiana. They are Haplogroup R1a1, which originated on the Eurasian Steppes.  These were the "Indo-Europeans" (Aryans) who domesticated the horse and whose language group formed the basis for today's European languages.  Some consider them the only "true" Vikings.

Haplogroup R1b

R1b is the most common haplogroup in western Europe, so it is no surprise that is is common in the project.  Because it is so common, most R1b's will need to test 67 markers to make a confident determination with regard to matches.  Your project admin recommends all R1b's be deep SNP tested to help advance the knowledge of this huge group. 

R1b1a2 WAMH

Some of our R1b1a2 members have a WAMH (Western Atlantic Modal Haplotype) logo on their member page.  This logo indicates they have one of the four most common 12-marker haplotypes in western Europe.

Three of the six R1b1a2-WAMH members are descendants of Josef STRAUB of Bieringen, Württemberg.  Two are American first cousins, while the third is a native and current resident of Bieringen.

The fourth R1b1a2-WAMH member is a descendant of Frantz Xavier STRAUB of Felldorf, Württemberg.  This family is the one whose descendant, Peter STRAUB, founded the Straub Brewery in St. Mary's, PA.  Despite the fact that the villages of Felldorf and Bieringen are just four miles apart, the STRAUBs of Felldorf are not closely related to the Bieringen ones.

The fifth R1b1a2-WAMH member is a STROOP who, though WAMH at 12 markers, is distinct from the other R1b1b2-WAMH members at 25 markers and at 37 markers.  His ancestor is Johannes STRUBE of Germany, who immigrated to Pennsylvania in the late 1700s, then settled in North Carolina.

The sixth of the R1b1a2-WAMH subjects is a STROUP whose earliest known ancestor, Joseph STROUP, who first appeared in Hamilton Co., OH, then settled in Shelby Co., IN, but whose origin is otherwise unknown.  An initial resemblance to one of the Bieringen STRAUBs at 25 markers (23/25) fell apart at 37 markers (28/37), amply demonstrating the need for R1b's to go to 37 or more markers.


Three of our R1b members are deduced to be R1b1a2, but are not designated WAMH.  One is a descendant of Philip STROUP of Clarion Co., PA.  He turned out rather unexpectedly not to match the descendants of Johann Pieter STRAUB, the 1733 immigrant to Philadelphia, who is the presumbed ancestor of Philip STROUP of Mifflin Co., PA, presumed father of the Philip STROUP of Clarion County.  Until a descendant of Philip of Mifflin County is tested, we don't know which connection is incorrect, the one between the two Philip's or the one between Philip and Johann Pieter.

The second R1b1a2 member is a descendant of Aloysius STRAUB, immigrant to Missiouri from Alsace-Lorraine, a location known to be the origin of many STRAUBs in the United States.  Will all of these STRAUB immigrants from Alsace-Lorraine turn out to have the same progenitor?

The third R1b1a2 member is descended from Elisha STROUP of Union Co., PA.  He has no matches in the project and only a handful of 12/12 matches outside the project, in other surnames.  Several of these matches are in surname BUDWIG, so an upgrade to more markers is called for to rule out the possibility that we're looking at an NPE.

A fourth R1b1a2 member is descended from Georg Michael TRAUB of Bretzfeld, Wuerttemberg, one of whose descendants immigrated to the U.S. and ultimately settled in Indiana.  He has a rare haplotype, with no matches above 12 markers.


This individual is a paper descendant of John Peter STROUP of Wythe Co., VA, but he is a high-level DNA match with the NEWHOUSE family.  There is circumstantial evidence to support that Jacob Jackson was adopted and that his biological father was John NEWHOUSE, grandson of Isaac NEWHOUSE, whom deeds show was a next-door-neighbor of John Peter STROUP in the 1790s. 

R-1b1a-2a1a-1a3 = R-L1 / S26 (Null 439)

One of our members is a descendant of Carl STRAUB, the 1881 emigrant from Wuerttemberg to Philadelphia.  He has a null value at DYS439, indicating the marker has been completely lost (or at least the indicators identifying the marker have been lost).  This deletion is a rare condition and is sufficiently distinct that there is a null439 DNA Project at FamilyTreeDNA.  The mutation is found mostly in the British Isles, but is also found elsewhere in western Europe.  Our subject resembles "Cluster 1" of this group, which is concentrated in England, but also found in southern Germany.

R-1b1a-2a1a-1b4b = R-M222 Northwest Irish

Another paper descendant of John Peter STROUP of Wythe Co., VA, with an NPE in his lineage has a haplotype resembling that of descendants of 5th-Century Irish warlord, Naill.  His deep SNP testing proves he is R-M222, the "Northwest Irish" subclade, and he has some near matches with Irish surname DOHERTY / DOUGHTERY.  This individual is offering to subsidize the testing of a male STROUP who is a patrilineal descent of John Peter through his son, George, or his grandson, Russell.  (Please contact project admin for details and conditions.)

Haplogroup T

Haplogroup T has been found in southern England, northern Spain, the Shetland Islands, and Germany.  (U.S. President Thomas Jefferson was Haplogroup T.)

T1 (old K2)

This individual is a descendant of Johann Valentin STRAUB, 1847 immigrant from Baden to Michigan, a descendant of Dionysius STRAUB (c1655- ) of Heidelberg.  His haplotype is unique, with no matches in the entire FTDNA, Y-search, or SGMF databases.

It turns out that STRAUB/etc. has more origins than expected, at least more than I had suspected.  We've also uncovered several bad connections and made some unexpected new ones.  I knew this project would be interesting; I never dreamt it would be this interesting!


If you want to increase the probability of making a match and speed up the progress of this project, offer to subsidize a test, even if it's with just $10.  Donations can easily be made through the project's General Fund (see below).

We currently have researchers willing to subsidize the testing of male individuals with patrilineal (direct male line) descents for the lines listed below. 

1.  Any male STRAUB born in and living in Europe who is not descended from a line already tested
(see List of Progenitors), one who knows his patrilineal ancestry back at least a few generations
free 67-marker test (offer by project admin).
2.  Martin STRAUB (1616-1676) of Heilbronn Dist., Wuerttemberg, but only one who does not
descend through Martin's son, Hans Adam STRAUB (1666-1726) free 111-marker test (offer by project admin).
3.  Mathias STROOP (c1660-c1740), Westphalia to MD in 1687 $100 off 67-marker test.
4.  Johann Daniel STRAUB (1743- ) of Northampton [now Lehigh] Co., PA free 111-marker test.
5.  Andrew S. STRAUB (1797-1858), PA to Waldo, Marion Co., OH free 111-marker test (offer by project admin).
6.  John Peter STROUP (1760s-1857), Wythe Co., VA free 67-marker test (offer by Glenn STROUP).
For a patrilineal descendant of John's son, George STROUP, or his grandson, Russell STROUP.
7.  Any STROUP/STROUPE with an origin in NC $100 off 67-marker test.
For the three descendants below, the offer is for a free_67-marker test
or to split the cost of a 111-marker test.
8.  Joseph STRAUB/STROUP (1800/1-1860), PA to OH to IN (offer by project admin).
9.  Michael STRAUB/STROUP (1811/2->1880), of Juniata Co., PA (offer by project admin).
10.  David Norman STRAUB (1864-1936), of Dauphin Co., PA
For a patrilineal descendant through any of his sons, except Harry Jacob STRAUB.

For all subsidies, acceptance of the subject is at the discretion of the donor (i.e., upon the researcher's satisfaction that there is a valid paper connection between the test subject and the ancestor) and the test subject must agree to sign the Release to allow sharing of his test results.  Please note that sharing of results does not necessarily mean sharing of identity.  Only the project administrator, FamilyTreeDNA, and genetically matching test subjects would necessarily know the identity of the test subject.

General Fund

In recognition of the fact that some individuals may find the cost of DNA testing prohibitive and that these individuals may be the only representatives of key lines in our genealogical research, Family Tree DNA has instituted "General Funds" to allow researchers to subsidize the testing of these key individuals.  The fund can also be used as a simple way to give someone a gift of DNA testing.  Please see this link at Family Tree DNA for more details.  And please consider a donation to the project as a way of bringing more lines into the project, especially to help some of our elder kin be tested who may not otherwise be able to afford it.  There is also a field on the donation form allowing you to make a donation in honor of a specific person.  The funds will be entirely collected and held by Family Tree DNA, but their dispursement is implemented by your project administrator.  You can inform your project adminstrator whose test you want subsidized with your donation or, if you wish, you can leave it up to the project administrator to decide where the funds can best be applied.  Please note that anonymous donations are not just anonymous to the public; they are also anonymous to the project admin.  If you want the admin to know you made the donation and/or have a special request for how it is to be spent, please notify the admin by email at the time you make the donation.

There has been an instance in one of my projects where a donor sent a prospective member a check, then the person never followed through by joining the project.  This situation can be avoided if the researcher has, instead, donated the money to the project's General Fund, because the money simply won't be spent if the person fails to join.

There has also been an instance in one of my projects where a donor agreed to fund a test based on the promise of a secure line to their progenitor, only for me to discover there was an adoption in the line.  In this case, the researcher had donated their money to the General Fund, and I caught the NPE in time to deny the subsidy to the test subject.  This situation is also a reminder to examine someone's line, yourself, before agreeing to subsidize their test not that there was intentional deception here, just flawed paper genealogy.

Bottom line:  before sending a stranger a check, please consider making a donation to the project's General Fund, instead.  And, please, in no case send money to me; I do not want the responsibility of handling it.
