The Thomas Allen referred to that married Margery - daughter of John Bryan - had a brother, Zachariah, and possibly Daniel.They left Tennessee the summer of 1819 along with Samuel Allen, Thomas Rattan, Levi Reeder, and others and went to MadisonCo., Illinois - the part they went to became Greene Co. in 1821. This Thomas is my direct ancestor. An attempt was made at one time to put him as a son of Erasmus, but at that time we couldn't connect a Zachariah to Erasmus and we know that Thomas and this Zachariah were brothers. Plus the Thomas that was a son to Erasmus was supposedly born in 1756 and our Thomas was born 1766 . Zachariah was married twice and supposedly had 25 children. It has been a while since I have talked to those Allen researchers and I don't know whether additional evidence has surfaced to link our Thomas and Zachariah to parents. I find it interesting that you also tend to link this Thomas with Erasmus and thought you might be interested in knowing what became of him.He died 7 Sept 1832 in Whitehall, Greene County. Illinois and was the father of 8 children. Thank you for all the postings - very interesting.
