Funny you should mention that. I'm Irish and white but my name (Eddy Robinson) 'sounds black' to a lot of people, and I wasn't aware of this until someone I was doing business with expressed surprise on our first meeting. I did a quick straw poll of acquaintances who I'd had first contact via email or seeing my resume and they confirmed this assumption. I can't say it's ever affected me personally though I wonder sometimes if it's a factor when I bid on a job and don't get a reply.
This article made me think more about the possibilities if I had picked some place other than California to live when I came to the US: http://daisysdeadair.blogspot.com/2008/04/on-having-black-na...
