Charles MAVES, MEWS, MEWES was from Stettin, Pommern. I wouldn't be surprised if the other family surnames were as well.
I have given you a few sites that you might want to check. You can see that Stettin is now Szczecin, Poland. Vorpommern or was called Pommern. It will probably be a difficult area to research. Though family search .org has some earlier data before 1800.
