John Maring appears to have been the John Mahring recorded in the 1860 census of Cumberland Township, Adams County, Pennsylvania. The census listed him as a 56-year-old farmer born in Pennsylvania, with real estate valued at $10,200 and personal estate valued at $1,000. He was enumerated in dwelling 481, family 537, with Sophia, George G., Rebecca, Jonas Mahring, and several McKinney residents. County-history and federal-claim evidence support a connection between John Maring and George G. Maring; John had died before the 1886 federal claim.
