The death certificate for my GGgrandfather John Oplicker lists Christopher Oplicker and Elizabeth Doyle born in Ohio as his parents. John was born in Millersburg, Hardy Twp, Holmes County, Ohio 15 Feb 1854 and d. 10 Nov 1914 same place. Does anyone have any additional information about John Oplicker (Opliger)? The name changes from Oplicker to Opliger to Oplinger as the generations progressed. I cannot locate John with Christopher and Elizabeth as parents on any census so far. Any help or lost cousins would be welcome!
