Sheila, I might have a surprise for you. I have a history of the Platz family going back to Adam Platz and his brother who came over from Germany thru Amsterdam in the 1700's and in this history it mentions Israel Platz and his family including Joseph. It was given to me in 1957. I will have it re-typed because it is hard to read and send it to you as soon as I can. I think we are related.
