I seriously doubt the people you work with were trying to hurt your feelings or make you uncomfortable. Many people do know where their family is from-Jamaica, Bahamas, English and African. I mean, it's not out of the question that you could know some of your family history. Some poeple change their last names after doing research of their family tree. I don't think your feelings are invalid at all, but I hope they weren't trying to make you feel bad. My really good friend is black and she is British, accent and all. She does know where her mother's family came from, but not so much her fathers.
