I can't think of the web site right now, but they research odd names. One lady was named "Velveeta"...who would name their kid after processed cheese? What I can't stand are all the trendy names. You go to any school around here and when they do attendance in the morning, it's Kaitlyn 1, 2, 3 , 4 , of course they are all spelled wacky too. Madison is the state capital of Wisconsin, NOT a girls name.
Vendetta isn't so bad. My only concern with names like that is the negative connotation that goes with the actual word, can people separated the word meaning from the name? I would never name my kid a name that they'd have to explain. "Hi my name is Vendetta, because mom hated dad and wanted to get his money, my brothers name is ****** cause she got him again!"
And yes cherry_cherry, in the US there are people from every country so we have lots of ethnic names. I just don't appreciate when you aren't from that culture and you name your kid with a word you don't understand or appreciate.
