Yup.
Ever heard of Gavrilo Princip? Princip is a title his family has gotten. Thing is his family's former family name, and the family name he was registered under in Austro-Hungarian documents, is also my mom's family name. Just that they are of different religions (which, in my country means, they are of different ethnicities as well), so I never thought much about it. I should have, though.
Gavrilo Princip is actually a pretty close relative of my grandmother's (pretty close for the standards of a country where everyone is cousin).
