This is the marriage license for my great grandparents Connie M Howard and Mattie Maddox dated 8 Mar 1914. Notice Mattie's listed age: 26. Mattie was actually 32 (almost 33) when she was married. For a researcher not as familiar with this family, that mistake could lead to looking for a birth date in wrong time period.
At least this marriage license had the correct bride and groom listed! (Unlike here.)
