Military Records are free, as long as they are for your ancestor. They also have the indexes to the Federal Census for Missouri, and census records, which I find helpful, if I just have a family or two in a county, I don't have to order the film. They have more records than just what is on this list, They are very helpful. Just ask if you don't see something. My only advice is, wait a week after the first request before sending the second , because they won't do two at a time.
Round trip varies between one week and three weeks.
