Need help to "fill in a gap" in my family line
My grandfather was John Edward Sherman b. 1894 d. 1966 m. Lillian Furler in 1917.
His father was John Blanchard Sherman d. 1939 m. Inez Hahn in 1867.
His father was Scott Sherman b. 1839 d. 1915 m. Ann Eliza Palmer in 1866.
His father was Stephen Sherman b. 1801 d. ? m. Marietta Sykes sometime before 1829.
I have a birth record for another Stephen who was born in Vermont in 1779. His father was Daniel Sherman m. Ruth Howard.Unless I can prove that he was the other Stephen's father, I am unable to go back any further in my family line.Can anyone please help me?
