"Republic of Texas: Poll Lists for 1846", compiled by Marion Day Mullins, shows:
Humberson, W.F. -- Anderson Co, TX.
Anderson was formed in 1846 mostly from Houston Co., but a little sliver of it was taken from Nacogdoches Co.You might check the 1850 census, where you could tell a little more about him.At least you could tell where he was born, and his age. Happy Hunting (^_^)
