False information on marriage records
One outcome of a surname study is the breaking through of some hard brick walls that are created when fictitious parents are given on marriage records. Usually it is the bride's parents who are fictitious. The fictions may not be intentional; in many jurisdictions the parents' names are not given, and a non-local groom getting a marriage license solo may be put on the spot and make something up.
