Thomas was born 1766 - no full date.His brother, Zechariah was born 8 Jan 1760........both in North Carolina.Margery born 1768.There is a marriage certificate for them - 26 May 1789 in Salisbury, Rowan Co., North Carolina.The records we have indicate they had 8 children.....Elizabeth(my ancestor)born 14 Feb 1790 followed by John, William A., Thomas, unknown Allen, Sarah, and Josiah. In looking through my notes for him I found the following: "The theory that his parents were Erasmus and Sarah Allen is supported by Robert Casey - however Robert Allen feels that this is highly questionable as the Thomas that was the son of ERasmus was born in 1756 - 10 years earlier than this Thomas and Erasmus does not mention our Thomas's brother Zechariah in his will - only a Thomas and a William. He believes that Erasmus is definelty connected but not necessarily Thomas's father." Robert Allen has researched the Allen line extensively and is very knowledgable - not many Allens he doesn't know about!Every time I run across some info I throw it at him and he always seems to know already!!As of yet, we have not been able to identify the father of Thomas and Zachariah. Thomas and Margary went to Tennessee sometime between 1795 and 1798.The 4 older children were born in North Carolina but the rest were born in Tennessee. Margery was the daughter of John Bryan and it appears that some researchers have put his father as Morgan Bryan, but others say, no way, Morgan's son was a different John!So, it is difficult to know which one is correct.
