So is he meant to be Kor, Son of Kor's brother or father or another male relation? Klingons practice primogenitor and while the TOS era was more military and less feudal (things seem to have reverted in the TNG era due to the lack of any real enemies to fight), Kor was very much about being a nobleman in the DS9 era--even if he only alluded to it with Worf and Martok. Mind you, despite the name, Kor may not have ever been the head of his Household. He was a Dahar Master but that is the result of his military service. He could be a cousin or distant relation while still having the blood of the House of Windsor or whatnot.
