Herz is a common German name. It means heart in common German, but I was told it also is a kind of stag and for Jewish people is something to do with a promise made to Naftali in the Torah. I have Herzes on both my mother and father's sides, but they are from different parts of Germany. My father's herzes come from Wesfalia and my mother's from Bavaria. I see you left this many years ago, so don't know if you'll get it. I am looking for info on the Herz family of Numbrecht and the Herz family from Markt Berolzheim today.
