I noticed that we have the same line of Henri; Daniel; Seth; and Elisha. My line goes further with William; Alton and Frederick. Frederick is my grand-father. After his father Alton died, he was adopted by is grand-father (mother's side) and had his name changed to Hildreth.
I am trying to find any living direct line relatives of William G. Gassett born about 1820, married Marcia Gould May 1841 in Mendon MA, they had 2 male children that lived to adulthood, William Gregg Gassett b/Oct 1854 and Henry Clinton Gassett b/ Jul 1856, d/ Jan 1934. Both lived in the Mendon, MA area.
