Similarly one may ask, what does MAC mean in Scottish?
Mac, Scottish and Irish Gaelic surname prefix meaning “son.” It is equivalent to the Anglo-Norman and Hiberno-Norman Fitz and the Welsh Ap (formerly Map). Just as the latter has become initial P, as in the modern names Price or Pritchard, Mac has in some names become initial C and even K—e.g., Cody, Costigan, Keegan.
Also, why is MC pronounced Mac? Actually, Mc is just an abbreviation of Mac so they should be pronounced the same. It means son of. Neither should be pronounced Mic.
Keeping this in view, are all MC names Scottish?
Strictly speaking, there is no difference between Mac and Mc. The contraction from Mac to Mc has occurred more in Ireland than in Scotland, with two out of three Mc surnames originating in Ireland, but two out of three Mac surnames originating in Scotland.
Does Mac come before MC?
In addition to sorting them under "Mac" and "Mc" respectively or choosing to sort them both under "Mc", it is known for Mc/Mac names to be placed in position before M.
