I don't know if this helps, or just confuses matters, but when researching the Denison family of Guilford, VT and Leyden, MA, I came across this guardianship record from (present day) Franklin County, MA: https://www.ancestry.com/interactive/9069/007705862_00916
In it, David Denison, minor son (above age 14) of Samuel Denison, decd., late of Fabius, Onondaga, New York, chose Stephen Blaisdell of Leyden as his guardian, dated 14 May 1822.
Samuel Denison, whose family were in Leyden and Guilford, had *supposedly* married a Eunice Houghton, but I have not been able to find any evidence of this, despite it being claimed in the Baldwin and Clift Denison genealogy (https://archive.org/stream/recordofdescenda1881bald#page/281...
I was hoping to find that Stephen Blaisdell was David's uncle through some relationship to a Eunice Houghton, but so far, I'm coming up with blanks.
Maybe the record will make more sense to those of you who have studied the Blaisdells. Hope it helps.
