What do you think of...?

The name Bruna.(BROO-NAH) That's my last name. I googled it and it said that it's German and Italian and that it meant dark-haired also, the female version of Bruno. I have jet-black hair or something similar to it. I'm Haitian-American. Both of my parents were born in Haiti and i was born in Florida. and I get my last name from my father side. Do you think I could have some German or Italian in me? I honsetly have no idea.
