The only source I personally have for George Lane's mother is her mention in his Vermont death record, where she is recorded as "Elizabeth Minot."
Do we know where the full "Elizabeth Danforth Abbott Minot" comes from?
FamilySearch suggests that Ephraim Lane married an Elizabeth Danforth Abbott, with no explanation for the Minot: https://www.familysearch.org/tree/person/details/L446-RHQ
And the sources on FamilySearch are, to be kind, not convincing -- it looks in places like multiple women have been confused.
