My mother's ancestors came out of Poland and eventually settled in Danzig, Freistadt. Her great-great grandfather's last name was von Grzenkowski and was considered an aristocrat with money and land...thinking maybe a dukedom or something similar. Somewhere along in our history Mom's G-G grandfather was considered a ladies man and gambled quite a bit and as a result lost the family fortune and eventually lost all the land to get money to gamble with. Consequently, the "von" was dropped and then the last name was changed to Grenert by my great-grandfather after my mother, and her two sisters (one died before this change) were born. That's about it for now.
