This is by no means a complete list; I'm sure there are others out there. Because the Mac/Mc prefixes and the lower or upper case letter after Mac/Mc are interchangeable, I have not included all variations for all the names. It rather goes without saying if you're looking for "McGregor" or "Mcgregor", the "MacGregor" listing will give you the same information.
