Haplogroup I is the second most common haplogroup in western Europe, next to R1b, while it is the most common haplogroup in Scandinavia. Overall, Hg I has a broad European distribution, from the British Isles east to the Ural Mountains of Russia and south to Anatolia and the Mediterranean Sea, but its strong geographic concentration in northwestern Europe has led Hg I to be nicknamed, the "Viking" haplogroup (though some consider R1a to be the only true Viking haplogroup).

I1 is the most common subclade of Hg I. Geographically, I1 is highly concentrated in northern Germany, Denmark, and southern Norway and Sweden. The most common subclade of I1 is the root or ancestral subclade, I1*. Subclades of I1 are rare to the point of not being genealogically useful, but no other SNPs as yet subdivide the otherwise large I1group.

In lieu of useful SNPs (the search for which is ongoing), varieties of I1 have been defined by Nordtvedt based on STR haplotypes. A modal haplotype for all of I1 would not be meaningful because the various varieties of I1 have not shared a common ancestor for thousands of years, but key markers do unify the subclade. Among European haplotypes, DYS455=8 is virtually exclusive to I1 and YCAIIa,b=19,21 is universal in I1 (highlighted in red in the table). DYS511=9 (highlighted in green in the table) has proven to be a useful marker for separating the AngloSaxon varieties from the Norse and ultraNorse varieties, which are 10 at that marker (highlighted in blue in the table).

Four CORBIN project members are Haplogroup I1. They fall into two varieties, each representing descendants of a single progenitor.

Ken Nordtvedt is the guru researching Hg I subclades (see his Excel spreadsheet). For a table showing modal haplotypes for Hg I varieties in FamilyTreeDNA marker order, please also see my HTML transcription of Nordtvedt's spreadsheet.

Red labels indicate markers that typically mutate more frequently than those labeled in black. Marker 464 mutates most rapidly of all and sometimes has five to seven counts (a-g), not just four (a-d).
(Empty cells that are darkened indicate tests not ordered.)

I1-AngloSaxon-2

I1-AS is the most common variety of I1. It is most frequent in the Netherlands, northwestern Germany, and Denmark and is present at lower frequencies in eastern and southern Germany, southern Sweden, and the British Isles. Varieties of I1-AS have been defined based on haplotypes by Nordtvedt (see his table of Hg I1-AS varieties).

¹Markers 48-60 pending (Batch 264: target date 8/18).

The value of 8 at DYS455 (red table cells) means these individuals are definitely I1, and they are a close match to the modal values of Nordtvedt's "AngloSaxon-2" variety. The values of 10 and 11 at DYS511 (blue table cells) are unusual for the AngloSaxon varieties of I1, which are usually 9 at this marker (green table cell). A value of 10 is usually an indicator of the Norse/ultraNorse varieties of I1, and a value of 11 is even more unusual (see Nordtvedt's chart). They have over a dozen full matches at 12 markers, some near matches at 25 markers, and a few near matches at 37 matches (all in other surnames), but their haplotype remains unique at 25 or more markers.

I1-Norse

I1-N is the most common I1 variety in Sweden and Finland and is the second most common variety in Norway and Denmark. Your project admin speculates that this line of CORBINs may have been among the Normans (the "north-men") who invaded France from the North, then England in the Norman Conquest — then some time later, South Carolina.

I1-Norse Modal Values

As per Nordtvedt. Key markers highlighted in red for I1, in blue for I1-N/uN, and in orange for I1-N.

CORBIN

87808

Pvt⁷, Pvt⁶, Culver Cox⁵, Napoleon Brewer⁴, Napoleon Bonaparte³, Samuel², Peter¹ — of Lexington Co., SC

#87808 bears a close resemblance to the modal haplotype of Nordtvedt's Norse variety of Haplogroup I1. Because he matches the modal haplotype perfectly at 12 markers, he has over 200 full 12/12 matches in the FTDNA database (all outside the project in other surnames). However, he diverges from the modal values at 25 markers, and even more so at 37 markers, so he has no full matches at 25 or more markers.

The values of 21,21 for YCAII are unusual, occurring in only about 1.5% of I1. This kind of change (from 19,21 to 21,21) can occur in a single mutational event known as a recLOH (recombinant loss of heterozygosity). In other words, the 19-count copy was lost and replaced by a second copy of the 21-count copy, in one mutational event.

What constitutes a match?
Matches in other surnames are usually mere coincidence, so please ignore them — I'll let you know when you shouldn't!
For 12 markers: 8 or less is a non-relative; 9-10 means only a small chance of a relationship; 11-12 means a possible relationship.
For 25 markers: 20 or less is a non-relative; 21-22 means only a small chance of a relationship; 23-25 means a possible relationship.
For 37 markers: 30 or less is a non-relative; 31-37, please see this Chart compiled by FTDNA.
For 67 markers: 55 or less is a non-relative; 58-67, please see this Chart compiled by FTDNA.
For any test: 0 matching markers, please contact NASA.
