After years of searching I finally found Levi Lyman Sr., who died 1799 in New Milford CT. Guardianship paper had Adam Fairchild in charge of Levi Jr, aged 15 at the time.
Levi Jr. left Adam shortly after 1800 and went to Dutchess Co., NY, where he married Sarah Cornwall and had known children of, Amy (who married Samuel Scott) Wager W., who married Adah Shattuck, and Levi. Also possibly an Elizabeth. Levi and Sarah apparently died in Dutchess Co but beyond Coleman's book, I haven't been able to find them.
Does anyone have any information on Levi Sr? Who his wife was, where married, born, etc.?? Sarah Cornwall - who were her parents?
