I have no date of birth for Aaron, but two of his children I have: Josiah (aka Joseph) b.1855, Elmer b. 1860. I am sure of these as I have been to the cemetery in St. Johnsville. I think 1825-1830 is reasonable for Aaron.
I found their father to be Aaron from the following:
"The family of which Fox Sponable of Fort Plain, New York, is the leading representative, is an old and honored one in Montgomery county. They have usually been engaged in agriculture and have been noted as a family, for their habits of thrift and energy. The present record begins with Philip Sponable, a farmer of the county, who married and had issue. (II) Henry, son of Philip Sponable, married Mary Cook. Children: . Lasena, married Joseph Kretzer; children: . Annie, married John Van Alstyn; . Joseph, married Susan Steenburg. . Nancy, married Joseph Plank; children: . George, married Catherine McGazer; . Sarah, married Charles Wyland. . Hiram. . Susan, married AARON CARTER; children: Joseph, Elmer and Elizabeth."
I found Josiah(Joseph) and Elmer in two census records residing with Nancy Sponable Plank (sister of Susan)in St. Johnsville.
I have also found an Erastus Carter who would seem to have a similar birthdate:
ERASTUS CARTER -------- Buried November 11, 1898 at the age of 68 Years 8 Months at Mindenville; cause of death Consumption.Funerals Attended by. Charles W. Kinney
Also:From the Utica Morning Herald, July 14, 1881 Erastus Carter, a Mindenville blacksmith, received a kick in the head, yesterday, from a mule he was about to shoe. His skull is seriously fractured.
JOHN CARTER: 1825 State Census Index Town of Oppenheim Fulton County, New York CARTER, John H. 5 18
Charles was born in Oppenheim, correct?
(Oppenheim is about 4 miles north of St. Johnsville and Mindenville is roughly 4 miles south of St. Johnsville.)
I have to search my records, but I am sure I have something on a Henry Carter in Oppenheim.
