Grunwald in Wusen/Basien

Hello,

I am searching for Grunewald. I have a Dorothea born in Benern on January 3, 1711. Her father was Petry Grunwald and her mother Anna (?). Petry and Anna were married elsewhere. In searching sponsors of their children, the towns Wusen and Basien come up. I found the records on LDS for these towns but they begin in the late 1800's. Does anyone know if there are earlier records?

Thank you,

Judy Gotter
