Looking for any info on John Mertz born 1801 in PA and married to Sarah Harmony. John died and is buried in OH. Can follow through to present with lineage through John's son: James Davis Mertz (B. 11/09/1837- D. May 17, 1911) via Wilbert Christian Mertz's children. Have hit a brick wall pertaining to John's birth place in Pennsylvania. Virtually no info on Sarah Harmony married to John Mertz. Any help, contacts or leads will be appreciated.
