It shouldn't bother you in the least Graham. These are "traditional" rules of clan kinship. Archaic and Victorian don't you think. These were the regulations explained to me some years back when my dear departed aunt took a keen interest in thing Scottish. I should add that it took some persistant browsing to find the quote that I posted. These old stuffy rules don't change what's in your blood. You're every bit as celtic as would be if fate had dealt those rules in reverse.
