A recently issued (no longer than 6 months ago) baptismal record of any Catholic party should accompany any case.
The baptismal record should have a section about the sacrament of matrimony.
It will list any sacramental marriage(s), dispensation(s)and annulment(s) as well as the reception of holy orders or entry into religious life.
If these are not present in the parish register, their sections on the record should be crossed out and read "no notations." Typically those sections are on the back of the forms parishes issue.
The Official Catholic Directory, published annually by P. J. Kenedy & Sons and kept in most rectories, provides addresses of parishes in this country.
