Looking for information on gr-grandparents J. L. SUND and Leopoldina Christine Henrietta LAURSEN SUND. Mrs Sund came from Denmark in 1869 with her parents, married J.L. in 1880 and settled in Polk Co. May have had homes in Luck, Milltown, and Half Moon Bay. They had 10 children, the eldest, Martin, was my grandfather. Any information would be greatly appreciated. Thanks much!
