Seth Warner says in his book that William Brown married Mary Smith, called Polly under bond dated 30 June 1800.Their daughter Lucy married George Tunstall 30 March 1820. He said that Lucy was evidently the only child of William and Polly to leave descendants, for William's only heirs were his seven grandchildren all children of Lucy and George. He did not name the children. Lucy died in 1850. Mary Smith was a relative of Orrin Randolph Smith who designed the Stars and Bars that flew over the capital in Montgomery, Alabama I had been told that Tabitha was a Twisdale also, but have never been able to prove it. So maybe it is Beckham. Would like to know for sure. If this William and Polly are yours, I will see what I can find at the Family History Center. Let me know if I can help more. Norma
