I just happened to see your post about your BOCK ancestors. My grandmother had a dear friend in Germany. I don't know what her given first name but Grammy called her "Do". Here is a photo of her and her family. Do is in the back on the right. My grandmother, Agnes Simon, is in the back center. I assume that Do's sister and her parents are the other people in the photo. I think their last name was BOCK!
Do they look familiar to you?
