Lee - STOLBERG in Hanover Church records

Lee,
previously you had advised me to seek out what church the STOLBERG/STOLLBERG
family worshiped in after them immigrated to Belleville, Illinois from
Hanover. I have finally located them, and at that time the Church was St.
Paul's Free Protestant Congregation, it was a German speaking congregation
and all records were kept in German. What do you think this would correspond
to in Hanover?
Thanks for any help
Denise

Dear List;
I am going to repost this request from a fellow list member to me. She is
asking for information about what churches in Germany would be related or
correspond to reformed churches in America. I have no idea but someone here
may be able to help her. Thanks in advance for your help.
