Re: McNaughton or McNaughton?
"They are both EXACTLY the same word, the Mc is actually the abbreviated form of Mac (and sometimes meic) and was usually written M'c (sometimes even M') with the apostrophe indicating that the name has been abbreviated (there are many other characters indicating abbreviation including two dots under the c)."
