Its been awhile since you posted so you may already have this info. Thomas A. J. Branch is my great-great grandfather. He was born in 1836 in Tennessee, one of my sources sites his birthplace as Knoxville, Knox County, but I have seen Fayette County listed in various sources. His parents are Benjamin Branch and Sarah Moore who were married in 1823. Thomas married Mary Francis Allen, daughter of Edmund Allen and Rebecca Smith. Mary was born Aug. 20, 1842 in Knoxville, Knox County, TN. I have info on his children, they had 11 total, one of which is Allen Branch, my great grandfather. Thomas died Sept. 9, 1914 and Mary died July 26, 1921, both buried in Allen Cemetery, Allen, Collin County, Texas.
Thomas' father Benjamin had a brother named Thomas who died early in life but with heirs. Watch for this Thomas when doing research.
I have info on several generations before Thomas, too much to post, please email me directly. Hope this helps.
