I see your post is quite old, but I have recently renewed my interest in family history. I attended Bethlehem Lutheran Church as a kid and remember Martha Tews. I believe the Tews family immigrated with several families in my family tree. I would have to do some digging and don't want to spend the time if you already have everything. Let me know how your search is going and if I can help you with anything in that area. My mother is still alive and knew the Tews family quite well.
