Alma, I've been working on this family too, I'm trying to track down information on Elizabeth "Betty" Ellsworth, dau. of Hannah Potter and William Ellsworth. I believe this family is descended from Aurthur Aylesworth (b. 1656 in either England or Wales) and Mary Browne. I'd be happy to share what I have, but I suspect you may have more info than I do-- I did not know that Hannah was the second wife. I do know that William Ellsworth's father was named Henry, which may account for the middle name of Nathan's son William.
