Hello all,
I'm Elinor Mintz's granddaughter. When I was younger, I interviewed my grandmother for a family tree project in school. One of the questions was about whether or not the family's original surname had been anglicized. My grandmother shared with me that in fact, Mintz was not her family's original surname-- it was the name of the business-owners her immigrant ancestors worked for. Apparently the Mintz family showed them great kindness, so my grandmother's ancestors (and your ancestors, in turn) changed their surname to Mintz.
Does anyone know is this is true? I'll be seeing my grandmother this coming Sunday and will ask her. If it is true, that may change the family tree significantly.
