Adair Co., Missouri marriage records list the marriage on 13 Sep 1941 of Bobbie Lee McCoy, over 21, of Sedalia, Pettis Co., Missouri, to Rose Riddle, over 18, of Kirksville, Adair Co., Missouri, at Kirksville, Mo, by H. E. Otway, Salvation Army Officer.

Unless this record is for the wrong Rose Riddle, she was not really 18. But there is no other Rose Riddle in the 1930 census of Adair Co., so if it is a different one, she would have had to move there sometime between 1930 to 1941.
