Interesting about the "Karl III Johan-Karl XIV Johan" - mix in history. The "official list" is probarbly written and edited i Stockholm. The children in swedish schools today don't learn it in the norwegian way. My father in law never during his lifetime 1920-1996 heard very much else about the name of the blothbath i Ronneby (severel thousands were killed by svear=sweeds in one day) but had to learn everything about Stockholm blood bath (I think 8 noble men lost their heads).
I wounder if Dronning Margareta will be swedish or danish? Maybe under "Kalmarunionen"? In Ronneby last year it was a drama play about this Queen of ours. Since this area belonged to Denmark. Kalmar is situated in Småland where there was from the beginning several chiefs/kings. Småland = Small countries, and the people there did not like the swedish king and his german soldiers. They prefered Nils Dacke, who by the sweeds is named a terrorist. My grandparents talked about him as a hero.
The one and only : ).
I'm not sure, but maybe a possible way to handle some problems that are, is to name Karl III Johan as a geneaological normal person: Jean Baptiste Bernadotte (AKA Karl XIV Johan, Karl III Johan and Profession: King). It's well known the family name is Bernadotte.
I'm sure I'm not the right person to replace fictions with facts and tear down the nationalistic walls built several hundered years ago :=). (As you maybe have heard of they are now on their way to open a third grave in Stockholm to find the remainings of Magnus Ladulås
http://www.geni.com/people/Magnus-Ladul%C3%A5s-kung-av-Sverige/3176...
but now they have opened 2 graves in Riddarholmskyrkan and it's not his remains in "his" graves. Maybe it's in a third suggested grave? The two first graves contents is from persons who lived 100-200 years later than Magnus Birgersson "Ladulås".

But it has been a good story told during many hundered years to people by the Eriksson-family from Dalarna.
