I, too, am searching for this Abigail. From where did you get her birthdate and birthplace? Her first children were probably born in Durham/Dover, NH, but some may have been born in Harpswell, ME. He witnessed a deed at Dover NH 1732/33; they went to Brunswick ME ca 1740 where they both signed deeds in 1740, 1741 and 1758. But he was in Dover NH in 1741 where she signed a deed. Again to Brunswick aft Jun 1748. To Great Cranberry Island ME bef Oct 1763. The 1790 Census of Mt. Desert lists only one Benjamin Bunker family but that included 2 males over age 16. We believe Abigail was by then deceased and he was living with his son Benjamin.
