I found Henry Totten in 1855 in Fulton County (Cass Township)
I've tried 1865 but no clear answer --lots of Tottens and various spellings of last names and first names. Write back and I'll see what else I can find and send you the 1855 image. IN 1855 a Wm Tottin is his neighbor(?) and a John
Totten is at the bottom of the same census page. The cursive T can look like a J or S so I'll try *otten and see what pops up.
