I am another McAdoo searcher who just found this forum. I am a descendant of Barnett McAdoo, b ~1777 in North Carolina and his wife, Frances Murphree. Barnett died in January 1858, and Frances ~1867, both in the area of Huntington, Carroll County, Tennessee.
Barnett and his wife had at least 12 and possibly as many as 15 children. My line is through his son Levi Pinckney McAdoo, who was called "Pink," presumably because he had red hair. Levi was born ~1811 in Tennessee. He married Minerva Ellen Harper, also born in Tennesse ~1815. Before 1830, they had moved from Tennessee to southern Missouri, to Brush Creek (Laclede County), roughly into the area of Springfield.
Their third son was Andrew Jackson "Jack" McAdoo, whose third son was Joel Alexander "Joe" McAdoo, whose first son was Clarence J. McAdoo, whose son was Harlan McAdoo, my father.
I have a tremendous amount of information about this family, but I am still in need of proof of Barnett's father. For a long time, I believed that he was the William R. McAdoo living with Barnett's son Stephen at the time of the 1850 census. It has been pointed out to me, however, that Stephen had a son William R. who was 20 at the time of the 1860 census, so the "100" next to his name in 1850 was probably a poorly written "10."
I also have a lot of information on other early McAdoos, most of it sent to me by other McAdoo searchers. I would be happy to help anyone in any way that I can.

P.S. I post family documents on both the email@example.com
and genforum bulletin boards. I will start posting them here as well. If you have a long document you would like to see posted, send a copy of it to me by snail-mail and I will type it for you and post it. I type nearly 100 words per minute, so typing something is not problem for me at all. Besides, this way I get to see more family documents.
