I am interested in your John Eicher, son of Jacob Eicher. I have an ancestor, John Eicher, birthdate unknown, who married a Tena Mathias. My John Eicher had a daughter, Mary Elizabeth Eicher, born in 1852, who married Jacob Carey. I grew up in Pleasant Unity,PA. The town is called Pleasant Unity. It is in Unity Township. I have other ancestors who lived in Hagerstown,MD.
