I'm from a family with a Mennonite and German Reformed background, we haven't been Mennonite for a couple generations though. I learned standard German in HS and College, and have a lot of interest in linguistics and got interested in the dialect primarily for what I'll call religious and academic purposes. There's an abundance of learning material online, textbooks, dictionaries, and there's plenty of resources in the Berks/northeastern Montgomery region
I don't know. Have you been looking for "us" before this thread? If not, then, you can't really find what you aren't looking for or aware of, can you?
