Dorene --thank you for your reply. I descend from John Ela of Conway later Fryeburg, a branch that is excluded from the Ela genealogy book. I had noticed that Mehitable also doesn't appear in th book and suspected she was from the same line. Since posting this query I had another researcher link Mehitable as sister of John based on a Conway VR listing. Do you have any clues or information on William, such as whether he served in War of 1812 or any clues on his parents? This is the current roadblock.
