I'm of Jewish descent (among many other things!), I have dark curly hair and I am often times asked about my ethnic background. My dad's family came out of Germany in the 1860s, and they converted to Christianity once they arrived in America. Through the years, a lot of "watering down" occured in his family-- the typical Caucasion "Well, I'm Irish and Italian and French with a little bit of Scottish." Curly hair was always dominant though, and occasionally a very Jewish looking person would pop up in the family. I guess things got mixed up even more when my parents married. My mother's family is Hispanic, a mixture of Spanish and American Indian (they all have stick straight, black hair.) In a nutshell, I look like a very tanned Jew with an Indian nose. lol
