Genealogy / Last name - Murzyn [33]

Merged: What does the last name "Murzyn" mean?

I am 1/2 Polish. My parents and grandparents were all born in the U.S., so I don't know much about my heritage. Every now and then, I meet someone from Poland who tells me my last name, Murzyn, means "black person" or a derogatory (slang) term for black person. Can anyone shed light on why this word is my surname? I'm very curious about it's origins as a family name.
