I am looking for information on my great-grand mother Anna Katherine Brunken. She was born 08/24/1848 in Hollwegen, Germany. She married Frederich Stover in 1870. They had nine children all borh in Germany except the last one. The family immigrated to the United States in the 1890's and settled in Sheffield,Iowa.I have not been able to trace the Brunken family back any further. Any information anyone might have on here would be greatly appreciated.
