Hello, I was just researching my Thomas line. I have found that Simeon Thomas b. July29,1803 that married Esther Coates in Henry Co,S.C. is a cousin to Martha Adeline Thomas b.1829 married Charles Austin Coates and after his death she married Charles brother William Elijah (Doc)Coates. Charles and William Coates are both Austin Marion Coates and Margaret Coons Sons. Martha Thomas' father is named Simeon Thomas too.He was born 1800 in Hickman, Tn. He is the great uncle of Simeon Thomas that married Esther Coates. Robbie
