I have totally different info than you do about Adam Allen--who in our family records is a brother of my ancestress Nancy Allen Shaver--who always said she was an "own cousin" (first cousin?) of Ethan Allen.My father thought she was a generation off in the relationship.Anyway, Adam did fight in the Revolutionary War and did migrate to Ky. He had a child Betsy by his first wife and 6 children by his 2nd wife Nancy.They were Elijah, William, Benjamin, Adam, Ethan, and Aaron.Other than my Nancy the only other sibling I know of was Peter who married Hannah Esarey.My father always said their parents were Benjamin and Sarah Powell Allen. Of course, he did not have a computer but he read and traveled a lot. What do you think?
