Henry Jones lists Maria Straub/Stroop, wife of Leonardt Planck, as the daughter of Henrich. Not sure which Johannes Stroop you're looking for. If looking for the original Palatine then Maria was his granddaughter. She was baptized 8 Oct 1750. Henrich had a son, also named Johannes. In a message dated 4/6/2005 3:02:33 A.M.

I am trying to find out how that Johannes Stroop is related to the Maria Stroop who married Leondert Planck of Athens earlier.
