Could you please answer questions on these uncommon names?

I had a friend who's father's name was Gunnar. I absolutely don't like that name! It makes me think of a old, hillbilly sitting on his porch with a shotgun!!!!! Mariposa is okay but kids are cruel and I think it would be a name that got made fun of a little bit! But when I think of the name, I think of a very pretty little girl!
