Willis Abbott is my 3rd great grandfather on my mother's side. I have him shown as Willis Simpson Abbott because the entry in the Lumpkin Co. marriage record book spells his name as Simpson. I have tried to research his parents but with no success. I strongly believe that he is a son of Matthew Abbott, the son of William Abbott and Mary Sarah Dennard but can't prove it. Matthew's brother John had a son named Simpson. The 1860 Walker Co, AL census shows two more children in the household, Willis, age 12 and Polly, age 10, but they are not shown in any other records. I have more info on Willis's descendants if you like. By the way, I didn't know about the marriage to Mary Davidson before.
