>St. Radboud of Utrecht (died 917) claimed to be descended from Radbod but the line of descent is unknown.

This doesn't support the presence of an unnamed son of Radbod, the saint's descent could just as easily be thru the known daughter.
I think the sensible thing to do would be deleting this profile.
