Unique enough that no one knows how to pronounce it---the only person I met who actually pronounced my name correctly on the first try was a substitute teacher I had in high school. I had been expected to have to correct her so when she said it right I went, "No, it's--oh, wait--yeah, you got it. That's a first." Even my friends pronounce my name wrong, no matter how many times I tell them.
But, there are a thousand or so of us around the world, according to Facebook. I've never met another with my last name but, apparently, they do exist.
