Mary, While my family has not lived in the St. Louis area, I was wondering if we may somehow be related. Ringkamp, as you are well aware, is a rather rare name. My family roots (Grandparents) start in Trenton NJ. I have turned up other Ringkamps in Pennsylvania and in Germany. I'll try to get more info on the Trenton Ringkamps. My Grandfathers name was Kirk.
