And my opinion is that this is exactly what our ethnicity is. We are all those things, we are not just one group of people to identify with. We are the sum of our people.
In my opinion, the origin of family is only that... the origin, it is where we came from, but it is not where we are. If you take any grouping, is it possible that every single generation in that family originated in that country? If your family is from Italy, for example, then your history is Italian, but, what if four generations before they came here, their parents ancestors came to Italy from Portugal? Wouldn't they still call themselves Italian if they didn't know about that connection? Record keeping a few century's back was not all that dependable. One should be defined by where they are, their routes are their history only. An important part of their family structure, but, doesn't define them. Again the fact that we do incorporate traditions in our culture is part of the definition of our culture. It's what make us, us!
In this country the generation of my grandparents, there was very little discussion concerning the links to other places. Some were French, but, never taught their children the language because they were in the United States and left France for a reason. A reason that they pretty much kept to themselves. That is one of the reasons that Family Search business are doing so well these days. Nobody, really ever talked about their origins.
