The only death date that I have is for Johann Conrad b. 9 june 1755, d. 1 May, 1811. Nor do I know if Johann Christopher, Casper or Micheal were married. Of the daughters I only show Maria Susanna b. 30 Dec, 1745 m. John George Schoeppl and Anna Sophia b. ca1749 m. Nicholas Gerlach. I don't have a daughter named Catherine. There was a dau-in-law Catherine Hoffmeister whose husband was Johann Andreas. Wish I could supply more.
