Meredith, thanks.It looks like George Adams b 1790 could be a brother or cousin of Reuben Adams b 1795 NC.Priscilla Robertson, Reuben's wife, father was named John Robertson, and her mother was a Thompson.
I have looked at James Thompson, RW, b 1752 and Rachel Baldwin (m 1773), as possible grand parent in-laws for Reuben Adam. The Thompsons had a dau Elizabeth that marriage info is not indicated (mother of Priscilla?), and theywent in a wagon train of 40 wagons, I've read, from Statesville NC, Iredell Co, to Wilson Co TN.At least two dau and s-i-l Henry Payne and John Patton also stopped in Wilson Co; the others went on to Maury Co TN. The Thompsons seem to have ties to Orange Co, so there could be another Thompson who was the father.
Elizabeth (?) Adams, Reuben and his sister Susan's mother, married 2nd Fendal Roland in Caswell Co on Jan 16, 1815.We have info that Susan was at the wedding, who married Lemuel Chilton, son of John Chilton also of Caswell Co (John's will 1777-1814 page 291). Simon Adams was a witness for John Chilton's will. Elizabeth Adam Chilton would have been born before ca 1780 probably.
I corresponded about the Simon who left NC ,went to Hamilton Co TN from Anderson Co TN, and only know that he appears to be too young to have been Reuben's father.I am confident that we will find that Reuben's father and perhaps your George and Simon's father or relative enlisted in the RW (leaving Mass.) and promoted to LT before being mustered out.My notes from elderly relatives had said the soldier's name was "Reuben- and he was kin to the Presidents."In any event we know that Reuben's father, and Elizabeth's husband had died before her 2nd marriage on Jan 16, 1815. I am guessing that I have to identify an Adams that moved to VA, became a Lt and then moved to NC after the war. I think Reuben's father probably m after the war to a younger woman.Since our Adams settled in the same area, I think that they were probably kin.
