Below you will see the family tree of George Vancouver (Captain). This is the version that has been sent to me by a direct descendant of his brother "John" This tree is the most widely accepted tree as to the ancestoral background of Captain Vancouver
Certain inconsistencies do however exist within this tree that are either overlooked or ignored by most who view it.
The name starts as "van Borculo" it last two generations like that and then suddenly changes to the name of the female line of the family "van Coeverden"
NOTE: In western civilization it is almost always a fact that the male name carries and the female name is dropped, that is however not always true in the modern world but 700 years ago it was almost a certainty.
either way it carries on in the van Coeverden name. The third entry of the tree lists a "Reinolt van Borculo (a.k.a. Reinolt van Coeverden)" he marries a certain N.N. and the last name continues as van Coeverden. Two generations later... another Reinolt van Coeverden marries yet another N.N. (isn't that odd for grandfather and grandson to both marry a person with the same initials??and no other info)
They carry on the lineage through the centuries to the fifteenth generation under Reint Wolter van Coeverden, who marries and moves to England this couple creates the sixteenth generation of Lucas Hendrik van Coeverden (a.k.a. Luke Henry Vancouver) he in turn fathered John Jasper Vancouver and the rest is history.
