I would be very interested in any research into this family as well. My wife is descended from John R. Brown 1797-186?. This John R. Brown is in Monroe Township in northern Harrison County in 1850 but is in Flushing Township in Belmont County adjacent to Freeport Twp. by the time of his death. He is buried in the Belmont Ridge Cemetery.
The 1820 Census in Freeport Twp. lists 'John R. Brown Jr.' and 'John Brown Sr.' and my hypothesis is that this is my John R. Brown and his father, which would make my John R. possibly the brother of James K.
