Your John Grindle b. 1822 may be my grgrandfather.I base this on the remembrance of my father telling me that he went to vist his uncle Henry at his farm in Ohio. If John is my ancestor, than he had a son John b. 1894, a long shot, but not impossible.My grandfather died in Logansport, Cass Co., Indiana in 1928, and is buried in Mt. Hope Cemetary there.Please let me know if you find anything more.
