I am interested if you have found anything more on your Timothy Allen. I am tracing an Ambrose Peter Allen from Ontario/Wayne ct. N.Y. Ambrose was born in 1814. I think his father's name was Spencer Allen, and his mother was Sophia Kelley. At this time the only Spencer Allen I can find is the son ofCapt.Timothy Allen, and Margaret Shaw. This Spencer was born in June 15,1795 in Middlefield,Mass. His father Timothy was born Nov. 25, 1759 in E. Windsor, Ct. died July 1832 at Westfield, Ma.
I am interested in your line because of the Lenawee ct. mi connection. Ambrose Allen moved to Lenawee ct. from Wayne ct. N.Y. around 1835. Ambrose neighbor was Seymour Allen, one of the names you list as being a son of Timothy. It is quite possible that Spencer is the brother of the Timothy you are tracking. I show a Timothy Allen being born April 11, 1782 at middlefield, Ma. same place as my Spencer.
