That's a very nice correlation Maven. :) I think you have an excellent grasp of the historical implications and seem to know a lot more about these things than other people. Did you major in History?
Ulf, do have an example of the education system?
When I followed Philippa's line from Mara to her Marriage to Edward III, I saw her Ancestors went from Ethiopia to Turkey, then from Turkey to Hungary. (most people are aware of Philippa's hungarian roots). From Hungary the line then goes to France then to England.
When you look at Philippa's Father's line, it goes through a long line of French,Norwegian and possibly Finnish Ancestors. (I chose Fornjot because he is the oldest Norwegian Finnish Ancestor of hers I could think of). http://www.geni.com/path/Philippa-of-Hainault-Queen-consort-of-Engl...
I'm pretty sure she has a Swedish line somewhere, but I'm not quite sure which Ancestor of hers to choose to find it.
Be the time Philippa is born in 1314; she is Ethiopian, Turkish, Hungarian, French, Norwegian and Finnish at a minimum.
While they refer to her as one of Briton's Black Queens, in reality, her Ethiopian Ancestor's were only one small part of her heritage, as you say Maven.
The more fascinating part is the travels through different countries, cultures and the custom of marrying the royals of one country to the royals of another country. Over a long period of time, you end up with a very ethnically diverse person whom you hope holds the best characteristics of all the rulers in the world at that times, as well as being able to learn so many languages, customs and adapt to so many cultures.
In your opinion, which Historical King or Queen has/had the most diverse heritage? Do you think they refer to these ethnic trees today when they do business today and say things like "Mara is our common ancestor, so we are family and as members of the same family we should get along"?
