I don't have a problem with removing Roger Benjamin as the son of Eustache IV as there is no mention of him in the overview, if others are in agreement however 1 think it would be prudent to extend this discussion to the managers of the Roger Benjamin profile.

Managers of Stephen de Blois, King of England,

I am contacting you about this profile: http://www.geni.com/people/Stephen-de-Blois-King-of-England/6000000...
.
Hello, I put this information on the Benjamin site at World tree DNA. A Dana Benjamin is claiming that this line is not verifiable and he is demanding that I disconnect Roger from Eustace IV. Does anyone have the needed proof? Thank you.
Sincerely, Norvelle Lopienski
