Humphrey Family Mysteries

Location: Chenengo Co., New York
Surnames/tags: Humphrey Keyes Ives

I, Drew Humphrey Morgan, have been able to trace my Humphrey lineage back as far as an individual by the name of "Hiram Humphrey" who was born sometime in the late 1820's to early 1830's. Census records indicate that he lived somewhere in the Guilford/Bainbridge area of Central New York until the early 1900's. In my research, I have noticed that there seem to be a lot of typos from historical genealogy records. One source states that Hiram's wife was Esther Mariah Keyes, another Esther Maria Ives. In scanning through "The Humphreys Family in America" online archive, I've noticed that the type printing was not always highly standardized and that a lot of the information therein must have been extrapolated, opening the door for error.

Is Hiram Reynolds Humphrey the father of John Judson Humphrey, my great-grandfather? Was his mother a Keyes or an Ives? Is there someone who holds the key to unlocking this mystery?
