I have just discovered that I have a RISSER ancestor from Lancaster Co. PA. She is Elizabeth Risser, born c.1740. She first married Peter SHENK, c.1760 and had a daughter Magdalena. Peter Shenk died in 1763. Elizabeth then married Peter WOLF and had several children. As far as I know she was still living when her husband moved to Tuscarawas County, OH c.1817. Can you place her in your Risser file?
