Most histories consider the period where Anjou was the seat of British royalty to be a period where England was essentially just another unassimilated French province ~ plus, most the folks there spoke GALLO, which isn't really French.
Think of it this way ~ an early version of the Hapsburg empire, but with one family in one town ruling over a dozen countries, more or less ~ or at least they were able to marry off their daughters quite well.
Going back to the late 1300s/mid 1400s there's a Bourbon princess who was married off to the king of Sweden. She wanted a nice house ~ as princesses in those days were wont ~ but there was no land for sale in Sweden at the time. In fact, in much of Europe land was never sold ~ only leased ~ it was considered rather sinful to sell your hard won land (people had died so you could have it).
What they did was LEASE SOME LAND for her house/castle/palace. This became the place where tradition has it that all Swedish kings were then born ~ even though they were actually elected up until the first Vassa king ~ and history claims he was born there ~ on the other hand this guy did a cross country skiing event (while fleeing from the Danes who were busy killing all the Swedish nobility) that would make a modern Sa'ami cross country skiing champion blanch. They do this annually though, so everybody gets to see if they are up to the stern stuff inside the Vassa king.
The national archives burned in 1697 or thereabouts so all Swedish history prior to that date is known ONLY from local title deeds, town histories, family traditions, entries in Bibles, or church records, foreign records, untrustworthy Norwegian, Danish, Finnish and Russian records, etc.
Most of any of my Swedish or Sa'ami ancestors were already in America before those records burned so I know they didn't do it. Somewhere in there ~ in the burned records ~ is a deal made between Sweden and Spain where Sweden provided expert surveyors to Spain to begin marking up America so it could be developed and populated with Europeans.
Premature anti-Frenchists... I respect their enthusiasm.
