I see this message is over 5 years old, but I will leave a reply anyway in case someone still needs help (including me).
I believe Wm Manton is my great great great grandfather. His daughter-in-law, Almira D, is my great great grandmother. She was married to Wm H Waterfield in 1877. Her maiden name is Sawyer and her father was James Warner Sawyer (b abt 1816) and her mother was Elizabeth (maiden name is stated as Best on Almira's death certificate, but that may be incorrect; b abt 1812). She was living with her son, Willie M, at the time of her death. I am planning on going to the courthouse next week to see if I can obtain a copy of their marriage certificate.
