CAN SOME PLEASE ANSWER MY QUESTION ILL GIVE YOU ALOT OF POINTS?

Well Lets see...Whatever your uncle (by marriage) is, doesn't contribute to what you are. As you said there were a lot of Italians immigrants living in spain so there maybe some italian in your bloodline. However to pinpoint one specific nationality would be a great task. Many, many of us come from numerous backgrounds and I myself am Norwegian, dutch, irish, swedish, german, English, and American Indian and i even think there is more in there but those are the ones I know about for sure. The best solution I would think is what your parents are. They are your closest relatives and closest to tracing any bloodlines. If both of your parents are 100% cuban then your DNA would more then likely contain More then 70% Cuban Heritage.
