Hi Chrisann,
The wikipedia site is good. If you need/want more information than what is given there, let me know. The church is St. Dionysius Evangelical... used to be St. Dionysius Ev. Lutheran. I have a few pictures that I can email a copy to you if you want. Their records (birth, confirmation, marriage, death) go back at least into the 1600s. Is there someone or a surname in particular from Steimbke that you are looking for? My surnames from Steimbke are
