Dunmore's War is often considered the first battle of the Revolutionary War, and the battle of Ft. Henry the last.  I wonder how many soldiers were at both?

Conrad probably descends from Wilhelm STRUB, the 1737 immigrant to Philadelphia who settled in Frederick Co., VA, but I haven't been able to make the connection.

1.  Marriage Record:

2.  Ohio County, West Virginia, Will Abstracts (online at the Wheeling Area Genealogical Society web site):

Conrad STROUP 31 May 1786  Bequeathed to: Wife Margaret. Sons Henry and John. Daughters, Margaret, Susannah, Sarah, Catherine and Elizabeth. Witnessed: John Caldwell, John Boggs and John McConell.  Executor: Margaret Stroup.  Note: Will proved March 1787

Conrad's daughters must have been unmarried or they would have been mentioned with their husbands' surnames; and we know John and Sarah were minors. 

3.  Samuel Gordon Smyth.  1909.  A Genealogy of the Duke-Shepherd-Van Metre Family.  New Era Print Co., Lancaster, PA (online at HeritageQuest at Genealogy.com):

p. 97	"Abraham Van Metre acquired settlement rights to lands in Ohio Co., Va.; these were located on the waters of Short Creek... A portion of this land, called Black's Cabin, and located on Short Creek, was the scene of the organization of Ohio County which was created out of the District of West Augusta, on Jan. 6, 1777, and afterwards established at West Liberty."
p. 98	Remainder summarized by DGM: at the 6 Jan 1777 proceedings at Black's Cabin, Abraham VAN METRE sold two acres of land to the county for the location of the county government; witness to this deed was Conrad STROUP.

This index to colonial records gives no indication what the record is, only that there is one, and my guess it's for having witnessed the above deed.

Waynesburg Republican, Waynesburg, PA.  775 pp. (Reprinted with index in 1977 by Bookmark, Knightstown, IN, sponsored by Greene County Historical Society, Waynesburg, PA.)  Not seen.  Extraction in next source.

6.  History: Local: Early Settlers, Petition for a New State: Fayette, Washington & Greene Cos, PA (online in the ftp archives of USGenWeb; contributed by Bill & Carolyn Montgomery).  An alphabetized list of names extracted from a petition in Howard Leckey's Tenmile Country and Its Pioneer Families, which includes:

John Stoop... Conrad Stroup...

The petition itself is not dated, but is believed to have been compiled some time between 1776 and 1780 when there was a movement to have a new state created from these three counties which were, until 1780 under the jurisdiction of Augusta/Ohio Co., VA.  There is reason to believe the list included names of early residents who did not actually sign the petition, but whose names were added to the petition from early county records by politically motivated backers of the movement.  So, while we don't know whether Conrad actually signed the petition, we do know he was in the region at the time.

7.  The Fort Henry Story: The Fort Henry Defenders (online at The Fort Henry Project web site):  In a three-day battle in September of 1782, a group of 47 men and their families succeeded in defending Fort Henry against a force of nearly 300 Amerindians and British soldiers in what has become known as "the last battle of the American Revolution."  The defenders later founded the city of Wheeling on the site.  Among those defenders was Conrad STROOP.

Name of Grantee	Acres	Local Description	Year	Book	Page
Stroup, Conrad	500	Wheeling Creek	1787	1	403
Stroup, Conrad	500	Wheeling Creek	1787	1	432
Stroup, Conrad	500	Wheeling Creek	1787	1	474
Stroup, Conrad	200	Wheeling Creek	1787	2	37

I would have guessed that these were purchased by a son with newly inherited wealth, but Conrad gives no son, Conrad, in his will, so I guess it was our subject buying the land, just weeks before he died.
