I have only just begun to look at the above two Mr. Browns in VA in the 1700s, but based on a VERY BRIEF review of some old posts on this message board, I did not get the impression that anyone suspected that these two men were part of the SAME overall Brown family.While I have done no "independent original documentation research" on this family, it APPEARS to me that an older Abraham Brown (born about 1700, supposedly in Scotland) married a Margaret Unknown, and they had the above Abraham A. Brown (born about 1730), who married Margaret Kirkham, as well as the above Cornelius Brown (born about 1731), who married Margaret O'Neal.
Abraham A. and Margaret (Kirkham) Brown had a large family, and their children included a later/younger Cornelius Brown (born about 1759), as well as a Peter Brown and a Robert Brown.The first/older Cornelius Brown (born about 1731) and his wife Margaret O'Neal apparently had only two children.Their son was Benjamin Brown (born 1763 in Orange Co., VA, and he served in the Rev. War out of the Wilkes Co., NC area; he married Jane Dozier as his first wife....Benjamin died in the Wilkes/Elbert Co., GA area).Cornelius and Margaret (O'Neal) Brown also had a daughter who was named Margaret Brown, and she married a Peter Brown.No proof, but I would not be too surprised if that Peter Brown was her relative....the above referenced son of Abraham A. and Margaret (Kirkham) Brown.
The son of Abraham A. and Margaret (Kirkham) Brown who was also named Cornelius Brown (born in 1759 in Rockbridge Co., VA) married Jane Rowland in Botetourt Co., VA in 1794.As stated above, Cornelius' brother Peter Brown married a Margaret Brown (his possible cousin, in my opinion), and Cornelius and Peter Brown's brother Robert Brown married a Catherine "Caty" Brown (I do not know if she was also a cousin).I note that Robert Brown ended-up in Elbert Co., GA, and that is also where the above Benjamin Brown lived at the end of his life (so another possible clue that these people were perhaps all part of the same overall Brown family).
If anyone has any information that supports or refutes the above, please let me know.In addition, if anyone knows of a living male Brown from the above family who could join the Brown DNA testing project, he should be encouraged to take the DNA test.
