Hezekiah Thayer married the widow Christian Aspinwall Thayer in 1729 (her first husband had been Moses Thayer). That much is well documented, but published genealogies disagree on the origins of this Hezekiah Thayer.
Some sources say he was the son of Cornelius Thayer and his wife Abigail, and was born in 1708. Others say that he was the son of Nathaniel Thayer and his wife Hannah, and was born circa 1696. (In either case, his wife's first husband was a close family member -- either a brother or a first cousin -- possibly a double first cousin, since Abigail and Hannah may have been sisters.)
Wikitree has two conflicting profiles for this man: Hezekiah son of Cornelius and Hezekiah son of Nathaniel. It would be nice to be able to reconcile these two profiles into a single profile that links to one set of parents, but discusses his Disputed Origins).
Evidence to consider:
I've not seen a birth record for either Hezekiah. In general, these families don't seem to have been consistent about registering births.
The names Cornelius, Abigail, Nathaniel, and Hannah all are absent from the lists of children attributed to Hezekiah and Christian, so we can't use family names as a clue.
Published sources that link this Hezekiah to Cornelius and Abigail include the "Thayer Family Memorial" book published in 1874 and a number of other older books that might be derivative of the Thayer Memorial, including the 1883 "History of Braintree, Vermont" and "Hudson-Mohawk Genealogical and Family Memoirs" (1911) by Cuyler Reynolds.
Published sources I've seen that link him to Nathaniel and Hannah are (1) the 1964 book "Genealogies of the Familes of Braintree, Mass.", by Waldo Chamberlain Sprague, which identifies some of its sources, and (2) a descendants list on the Thayer Families Association (TFA) website, which does not identify its sources, but apparenlty is based on relatively recent TFA publications I've not seen.
The entry for Cornelius and Abigail in the Sprague book states "There was no son Hezekiah as given in the Thayer Memorial (1835) and elsewhere."
Legal documents related to Nathaniel's estate (quoted by Sprague) name a Hezekiah as a son of Nathaniel and Hannah.
Considering the foregoing, I'm inclined to pick Nathaniel and Hannah as Hezekiah's most likely parents. This is based primarily on the presumed greater reliabilty of the late-20th and early-21st century publications, as well as the fact that Sprague identified some of his sources.
I'm still bothered by the absence of children named either Nathaniel or Hannah. However, I note that this Hezekiah would have been 33 years old at his marriage to Christian, making it likely that he had been married previously -- maybe he had used his parents' names for earlier chlldren who have been lost to history.
What do others of you think? Is there relevant information in sources that I haven't seen (such as articles in the NEGHR)?
