Hello celi-nege, I'm glad to hear you enjoyed the first game for the most part and are looking forward to the sequel.
As for the name, yes, this has been mentioned before. I would say that this is a fantasy game and I never really meant for any of the names to be directly held up to real-life counterparts. I drew from a mix of French, Spanish and Italian and plain just made some of them up. As someone has already pointed out, Frederique is the feminine spelling, as well - I just prefer it that way.
Thanks for playing
