I believe this Conrad Kurtz was a Jr. His parents were Conrad Kurtz, born bef. 1735 and Elizabeth Cleaver. They had 5 known children: George, b. 1764, Conrad (Curts), b. 1766, Martin, Elizabeth and Jacob, b. 1780. I have more information on Elizabeth Cleaver's parents if you are interested. I also have some information on most of the children.
