To the people searching these two names. I strongly suggest you check records in Lewis/Mason Counties in NE Kentucky. (Mason was the parent county for Lewis which was created in about 1802) There were several THOMAS families in that area. One George THOMAS, born 1771, son of Michael THOMAS of Germanna Colony in Va. I don't have the names of all of George's children, but it makes sense that he would also have a son named George. And the age of the George you are seeing would fit. As for William Isaac THOMAS, both of those names were brothers of the George THOMAS I mentioned in above paragraph. Check all the records in these two counties and also check Carter County which is right next door and was once part of Mason Co. Ky. Knowing the parent counties of this area is essential since there were many divisions and split offs of various counties. The area was under a wild variety of county names from Kentucky Co, to Ohio County, to Fayette County, to Mason Co, etc. Sue
