Mary Jane Warren Furman was born about 1829. Her daughter, Angeline, I am guessing was born between 1847-1850.She married Almeron C. Chaffee and they had three children:Edgar Coleman, Carrie, and Wells.
Edgar Coleman Chaffee was born 11 September 1870, Rochester, Minnesota and died 28 May 1941, Corning, NY.
I'm afraid these dates are the best I can do at this point.
I'd love to be able to obtain a copy of Edgar's birth certificate but have not been able to find a researcher to do so.
