Hello Margie: Know Zimmerman was a popular name but just wanted to pass along that on one of the census I copied in the 1810 PA. census of Dauphin, Fayette and Franklin counties there is a George Zimmerman with a household of 10. In the 1820 census of Lebanon County - Heidelberg Township there is a "Widow" (no first name) Zimmerman with household of 2. Also a John Zimmerman with a household of 9. Don't know if this are yours or will help but just wanted to pass it along. Ahlive
