I am a Planck (Ver Planck) researcher, as well. I have an Anna ver Planck b.1764 in Oak Hill. She was the daughter of Johannes Planck and Catharina Schuh. I have these Plancks back about 4 generations and they were Palatines. My Anna married Georg Benn about whom I have written several articles because he had the distinction of fighting on both sides of the Revolution. Only one side, however, was voluntary! I am always interested in hearing about Plancks, ver Plancks, Planks, etc. Kathy
