My great-grandparents immigrated from Holland. They were Benjamin and Gertrude Oldenburger. Ben and Gertruded were first cousins, so her maiden and married name were the same. Their children were Fred, George, Henry, Ben, John, and Emma. Fred was my grandfather and his daughter, Mary Oldenburger Baldwin, is my mother.
Ben and Gertrude lived in the Waverly, Iowa, area.
