Polsar is buried at St Johns as are all of our direct ancestors. There are several books that indicate Blthasar (Polsar) Sigman was at Kings Mountain,he was a Blacksmith as were many of his descendants,your Aunt Katherine donated a Beer stine and a pair of hand made scissors that came from Germany with the first Sigmans,to the Newton Museum. I have a ring Polsar made for his wife from a nail until he could by a gold one.
