My name is Don Spade and my great, great grandparents,Jacob A. & Emerelle Spade moved to South Dakota from Iowa about 1900. They trace back to John Spade from Germany who fought in the Revolutionary War. I only have record of him having one son, John. He married Elizabeth Bowersox (Bauersachs) and they had 12 children who together had about 75 children (if my details are accurate). This is the link to the website where I have this part of the tree ---
