Hello - The original family name was MUNTZ,with an umulat over the letter U. It is now MENTZ, for ease of pronounciation. The family orgins were from NOWY ZIELUN, POLAND. The name given during the German partitioning was NAU ZAULUN. Is there anyone out there with common threads with me ? Thanx in advance. Chet I heard of an uncle KARL MUNTZ who served in the German Navy prior to World War II.
