Ernest Christian's marriage 1893/1894?

Dear Listers! I have tried for many years to find the marriage record for this couple: Ernest Charles CHRISTIAN, born Goodhue Co., MN Nov. 18, 1867, grew up in Lyon Co., MN Anna Marie URNESS, born Fillmore Co., MN June 12, 1869, grew up in Pope Co., MN The 1895 census Lyon Co., MN: https://www.familysearch.org/ark:/61903/3:1:S3HY-DB59-ZS6 The 1900 census Lyon Co., MN (married for 6 years): https://www.familysearch.org/ark:/61903/3:1:S3HT-6XMS-FR8 The 1905 census Lyon Co., MN: https://www.familysearch.org/ark:/61903/3:1:9Q97-YSYD-77X The 1920 census Hennepin Co., MN: https://www.familysearch.org/ark:/61903/3:1:33SQ-GR6G-GPJ The 1895 and 1900 censuses clearly suggest they must have been married shortly before 1894, but I cannot find their marriage! Any suggestions are very welcome! Very sincerely yours,
