I have a hardcopy of the index for the Alcorn County, MS Colored marriages from 1866-1870, 1892-1903 and 1913-1921. Email me and I’ll gladly do a lookup for you. It will tell you the person’s name and what page their marriage license is on. With that information, you can write to the county courthouse and obtain a copy of the actual license or record.
