Small suggestion for Frisian naming conventions

[Polskers]

Instead of using the German naming conventions for Frisians (von ___sson/sdohter), I have a suggestion to use instead for what it should properly be according to Frisian grammar.

from_dynasty_prefix = "fan "

male_patronym = "ssoan"
female_patronym = "sdochter"
prefix = no

That should be the replacement for the Frisian culture naming conventions, patronymic/matronymic, etc.

Just floating that out there. Hope it is considered!
