I see that the Goan Catholics have names like Bosteanv and Foransik:
https://en.wikipedia.org/wiki/Goan_Catholics#Names_and_surnames (in English)
Are these names specific/limited to Goan Catholics? Meaning: those names are not used by other Konkani peoples?
If not, then I don't think that they will need a separate category. All Goan Catholic names can then simply be listed under "Konkani".
But if yes, then I would certainly welcome the introduction of a usage along the lines of "Konkani (Goan Catholic)".
