no, for heaven's sake don't go getting into arguments about a baby's name. Nobody's stolen anything. There will be zillions of girls in the world with the same name, maybe even with the same middle name too; they're not trademarked. That's how absolutely *everyone* gets their name: their parents hear it attached to someone else, like it, and use it for their own kids. I've got the same name as a cousin of mine and neither of us has ever been the least bit bothered.
This is totally NOT worth starting a feud over, honestly.
