Below is an essay written by a Mr. Adrien Mansvelt, resident Vancouver Consul General of the Netherlands in the early 1970's. This is the version that has been accepted by everyone involved (i.e. governments, media, families and historians) only because there is no other explanation to the origins of George Vancouvers' family.
Throughout the entire 2nd part of this article you will notice that such terms as accepted, possible and assumed are used again and again. I find it difficult to believe this story due only to the fact that these words are used again and again throughout.
The statement that the van Coeverden family is the oldest in the Netherlands is an exaggeration in itself. There is no proof of this what so ever, certainly I am not saying that this family didn't have lands and titles (there is absolute proof of this) but in no way will I believe that this family is the original "family of the Netherlands.
The over indulged story begins at the top of the second part, whereas the author is making assumptions based on no hard physical proof
