Well, I have some suspicions, based on the censuses.
In the 1900 Census, There is a Jay D Pellet, with wife Anna L, daughter Ellen E, and father Jedediah.Later censuses only find the possibility of Ellen in the 1910 census, listed as Hellen Pellett, a servant in Perry, Michigan.
Earlier censuses show his name as actually being James, with the marriage to Anna L being his second.He can be found (as can his father, Jedidiah and mother Helen) in Chehasing, MI, Brant, MI, Oswego, NY, and Ira, NY.At this point, I suspect that Jedediah is the son of Jedediah and Tryphenia Pellet, also living in Ira in 1850.
If this is the case - this line goes back as far as Thomas Pellet of Concord, born abt 1635.
Hope this is a help.If you'd like an excel spreadsheet with the census information on it, I'd be more than happy to supply.Also, if you'd like more information on Jedediah (sr)'s line, just let me know.
