My research is on Peter Risch family from Bergen & Ludwig Bender family from Kirn. Bergen is about 3km west of Kirn. Both emigrated to city of Green Bay, Brown County, Wisconsin in early1850's. Ludwig married Dorothea Risch,daughter of Peter. The other daughter, Caroline Risch married my great great grandfather August Speerschneider from Bad Blankenburg, Thuringen here in Green Bay in 1853. August came to Wisconsin in 1849. Ludwig Bender was a witness on August's naturalization forms. I would like to contact anyone working on these families. Other possible surnames might be Wolf {or Wolff} and Brenner that may have come from same region. Paul Speerschneider.
