- There were a lot of Dyers in Cape Elizabeth, but her parents are a mystery. She in fact appears as a "lost Dyer" on the best Dyer family forum on the web (at http://freepages.genealogy.rootsweb.ancestry.com/~dyer/ and http://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi?db=lostged ). There is much literature out there on the Dyers, but I've found no good leads on her parentage specifically. The list of Ephraim Clark's marriages does not say that she was a widow when married, and this is noted in other cases.
How might she be related to the family Anna Dyer, wife of Samuel McLellan? Many Hannah Dyers appear in Underhill, The Descendants of Edward Small, including the Anna Dyer who married Capt. Samuel McLellan, but not this one. Both that Anna (I1037) and this Hannah were married on Cape Elizabeth in the early 1770s.
There is a Jabez Dyer, "formerly of Cape Elizabeth," m. Lydia Dyer, with children Jordan, Hannah, Jabez, Jr.. See: "Records of births and deaths in Hartland, Maine," Collections and Proceedings of the Maine Historical Society 9 (date?): 415.
Might see: Ebeneser Alden Dyer, Ancestry of William Dyer, "The Abington Pioneer" (Whitman, Mass.: Dyer Association, 1911). This has a series of Dyer family studies in it.
There is a Dyer family in Cutter, but I don't see her there. Cutter focuses on Massachusetts, Rhode Island, and Connecticut. Little discusses a Dyer family that seems a likely possibility, since he leaves lots of loose ends, but Hannah is not included. [4, 5, 6]
