Frank,
Interesting find for July 1860 but, I show John and Grace in KS during the August 1860 enumeration right after they were married in Bourbon Co., KS. Also, in the IN July 1860 enumeration it shows John "serving" but, John's enlistment records show him enlisting in the 2nd MO S.M. CAV in April 1862. Every record I have points to his birth taking place in PA but, really appreciate you taking the time to forward.
