I have done quite a bit of research on the Coshocton/Franklin Benjamin Fords. The Harpst and Paine names are still a blank to me. There is some vague evidence that Benjamin was born in Dudley, England in 1803 and that he had an older brother in Roscoe, OH.
I have his son, George Ford's Civil War military and pension records and much of the time line of his unfortunate life after being a prisoner at Andersonville until his death in 1918. His younger brother, Albert, died in 1879 from complications of what appears to be TB from the war. He died in N. Topeka, KS. I can only guess that he was "taking the cure" at a TB hospital. He is buried in Columbus.
Albert's wife Sallie (Sarah A. Johnson) raised their children Charles C (10 Dec 1872,) Harry P (14 Mar 1874) and daughter Alberta (20 Apr 1879)on her own. Sallie died around 1923 in Columbus.
I see your relative Jackson V Ford married Luretta (?) Moore in Franklin County in 1897 (the lsiting appears on a copy of marriage records I ordered from the OHS.)
I live in Rhode Island now but I grew up in the Cleveland area. My grandfather Raymond Clare Ford was born in Columbus 25 Nov 1897 to George William Ford and Elizabeth Sophia Hauck. He had two younger brothers, Henry, b 1900 and George William, Jr, born 1904. Henry died in 1991 in CA and GW died in Denver in 1988. Raymond died in Arizona in 1972.
