I know there are soooo many Armstrongs in Augusta Co., VA., that it is hard to keep them straight - I am trying to find a connection between Thomas Armstrong who m2) Mary Ann Lafferty (Stewart), widow of James Stewart (killed by Indians in 1757). He already had a son, William Armstrong, by his first wife. I am wondering if his son William was the William who married Elizabeth Erwin, d/o Jared Erwin. I have seen many postings regarding his son, William, JR., marrying Catherine Friel. This is what I know- William Armstrong who married Elizabeth Erwin, in Augusta Co., VA., 1788, was thought to be a brother to John Armstrong, who was thought to marry Agness Erwin (also a d/o Jared Erwin); however, I am beginning to wonder if he did not marry Polly (Mary) Crawford, as no record of a marriage for John and Agness exists; however, there is one for John and Polly (1790, Augusta Co., VA). The William Armstrong, Jr., who married Catherine Friel married in 1793; so he was contemporaneous with my William Armstrong (marrying within a 5 years of each other). So, I guess what I am looking for is the proof that the William who married Catherine was indeed the son of William who was the son of Thomas. Or, in the lack of direct evidence, has anyone found any documents which link the Thomas who married Ann Lafferty Stewart to the William who married Elizabeth Erwin. Does anyone have a source or sources which link all three generations? I am not looking for circumstantial evidence- I have more than enough of that in the way of the Chronicles of the Scotch Irish in Virginia. Does anyone have or know of a primary source that helps clear this mess up ?
