Debbie, do you have the 1860 census for Lunenburg VT? On page 60 there is a listing for Simeon age 37 and probably his parents Stephen and (if I remember right), Almira. He's a bit off on the birth year though.
I'm assuming you have him in 1901 in Sherbrooke? DOB 9 July 1827..
I also have a tickle in the back of my memory for Simeon, I'll check my records and let you know...
Either way they're all related one way or another... so howdy, cousin!
