I found an entry in Missouri, Marriages, 1750-1920 for the marriage of Robert Ferguson and Ellen Stanton in St. Louis, St, Louis, MO on 22 April 1861. I tried to order a copy of the certificate but copies of Missouri records are not available through Vitalcheck. Is it possible for me to get a copy of this document through another service? The entry in the book does not give me much information. I wonder if there is a reason they aren't available through Vitalcheck- maybe the actual certificates were destroyed?
