OK, I understand what you are saying about the geography. So, for example with the group that settled in the Bahamas, you would just categorize them with all Palatine Immigrants, but also under category for Bahamas? I don't know if it would be important to anyone, but one drawback of that scheme is that you could find all Palatines, or all Bahamians, but you would not be able to look up all Bahamian Palatines.
I have not surveyed the entire list (which I think is 88 profiles) but I suspect that most people in the category "Palatine Ancestors" are actually Palatine immigrants. It might be less work to rename the category and then start a new Ancestors category.
Also what do you think about a third category, for Descendants?
