If you haven't already found them, the records for Swan Lake Visitation are on FHL US/CAN microfilm 1703910, items 5 through 7. But this only covers the period 1907 to 1989 (when the church closed). Before 1907, church records would be from St. George (FHL 1703718 & 1703719) or New Ulm (FHL 1685740 & i685741).
