Ok,
Here's another question, my understanding is that "Mac" means son of. I sort of assumed that all Scots would have been the son of someone, therefore, why are there some Scottish names that do not carry this. For instance, Scotland appears to have lots of Millers, the last name I would have thought of as Scottish (my father always insisted it was). In any case, why are there no "MacMillers" or Millersons or some such derivation.

Anyone know how this works?

Thanks,
