Is Isham the One?

Finding a name like Isham Rainey in the 1830 census, right in the same Georgia county where my third great-grandfather Thomas Rainey had settled, was encouraging. As rare a name as Isham might have been, though, that was no guarantee that Thomas' neighbor by the same surname was his father. I had to wonder, is this Isham the one? Or was he a brother, a cousin, or even someone totally unrelated?

Granted, Oglethorpe County in 1830 had thirteen thousand residents. I suppose there could have been a name twin in the mix of a crowd that size. But Isham was indeed a less common name. Though an infographic from Ancestry.com—not surprisingly, the genealogy company features details on many given names—attributes an Arabic origin to the name Isham, it also mentioned that according to their data, the country with the most men named Isham is the United States. But don't assume that's today's details; according to that same infographic, the year in which the U.S. had the most people born with that name was 1840—just about ten years after this census record helped me spot that Rainey name.

So, where did such a name come from? One quick detail from Wikipedia noted that Isham is actually the name of a village and civil parish in Northamptonshire, England. It apparently became a surname, also from England. Eventually, as names sometimes do, that surname became a given name; third U.S. president Thomas Jefferson, for instance, had a maternal grandfather named Isham Randolph (though his own mother's maiden name was Isham). In fact, I found a genealogy book filled with details on eight hundred years of family history for one line claiming that surname.

Does that make this Isham Rainey kin to the famous families of colonial America? I doubt it. But I did find an interesting document, filed in 1844 in the Georgia county where Thomas Rainey had, by that time, moved, naming him and another man as administrators of the estate of the late Isham Rainey, senior, of Mississippi.

While that document doesn't necessarily explain the connection between Isham Rainey and Thomas Rainey, the five hundred dollars bond posted by the two named administrators certainly infers more than a passing acquaintance in the old neighborhood.
