Craig, Funny you should ask about that. I just came across something the other day about "being true to the Bruce" in Ayrshire. They were talking about the McAdams, but if it's true, then it applied to other Lowland families with Mac/Mc surnames. They supposedly changed from Mac to Mc in defiance of the British and added two small hash marks (underscore lines) under the little "C" in McAdam. This was supposedly recognized in Scotland to stand for remaining true to the Bruce. It was also supposed to be an indication of being Protestant instead of Catholic. The Catholics for some reason remained "Mac." That certainly didn't apply to emigrants to what is now Canada. They were all recorded as Mc at first. Then they started dividing into Mc and Mac in the 20th century, but it was mainly down Irish/Scottish lines where I grew up (Cape Breton Island). Allene
