I know this is years later, but I just noticed your posting regarding Morris Zaretsky. He would be my great uncle.
According to my records, if this is the same Morris Zaretsky, he was born in Drohiczyn, Belarus in 1896 and died in 1973.Though my records show that he married a woman named Mollie (not Rena), he had 2 children Mildred and Henry.Henry shortned his last name to either "Zare" or "Zaret".
Mildred (died circa 1995) married George Melman (died in 2001) and had 2 children (both girls).I believe one was Jan and I don't the other.Jan married a man with the last name "Marion" and that's where my family tree stops.
Do you have any more information for me?Seemingly, we have a connection here.
