I'm shocked and disappointed your Realtor isn't assisting you with those details. These aren't unusual questions you're asking and they should have an arsenal of resources for you. Have you asked them to help you out with this?
I live in the Oak Ridge section of Jefferson Twp, but don't know of any Protestant churches in the area. There may be one in a neighboring area. If you go to the Jefferson Township website, there's an information packet there for you to review. You'll find it on the
home page.
Good luck!
