Kreis Butow

I was recently given this information as the possible locale for my
JEKEL/JAEKEL/JAECKEL relatives:

Chrostow, 54�13' North, 17� 56' East
Germany, Provinz Pommern, Kreis B�tow.

This family is Catholic. Any ideas on how to research the catholic church
records there to try to find the family?

Any ideas welcome.
Regards,
Joe
