I am looking for further information on the family of John George Ziegler born February 16 1793 in Bavaria to Christoph Ziegler and Margaret Grewel. He died December 30, 1858 in Norwalk, Monroe County, Wisconsin. He married Anna Mary Schraud in 1825 in Halsheim, Bavaria. She was born 1794 and died in Germany. John George and his family immigrated to this country shortly after the death of his wife. They settled near the East Bristol area of Dane County, Wisconsin. Eventually several members of the family, including John George, ended up in Monroe County, Wisconsin.
His children were Michael, John, George, Mary and Nicholas.
I would appreciate any further information on this family.
