Patronymic Last names
In Scandinavian parish registers, patronymic last names which end in -sen, -ssen, -son, -sson or a few other variants and -datter or -dotter are often abbreviated -s. and -dt. or -dtr.
All the indexing of the records follows the standard of indexing exactly what is in the record. However, Family Tree's current standard is to not use abbreviations. This is resulting in numerous data conflict flags of, for example:
Margreta Asbjornsdr., "Norway Church Books, 1815-1930" has a last name of Asbjornsdr, which is different from Asbjornsdatter.
The various search routines on the website recognize that Ols, Olsen, Olssen, Olson, Olsson, Olzen and Olszen are all the same name and that Olsdt, Olsdtr, Olsdatter, and Olsdotter are all the same name. The Quality Score routine should as well and not flag a data conflict error.
