Except that she is a teenager, there is no reference otherwise to her being married already, while marrying at her age was not so-abnormal in her era it is unusual enough to a modern audience that it is hardly something that would be slipped into the show without comment, and they very much treat it as being her first name in the show. Once again I think it is either an inside joke about surname Gomez semi-accidentally being used as a first name in the franchise, or more likely just confusion (or apathy) on the part of the writers.
