A knight in the family

A real knight, that is. My mother has been out visiting my aunt and her new husband, who is a very distant relative of ours. My aunt and new uncle met because they were both doing genealogical research on our family. My mother found out from them that my great-grandmother's branch of the family is descended from a knight from the Alsace-Lorraine. When he was knighted he changed the family name to Von Zorn ("from the Zorn river", which is a river that runs into the Rhine in Alsace). He and his immediate descendants owned some castles, too, though only one is still standing. My branch of the family came over to South Carolina in 1735, and at some point started calling themselves just Zorn. Pretty cool.
