Notice that they didn't say you had to be a MacNaughton by blood or name, but just that you identified with the tartan in some way. That's what many of us have been saying -- Jimmy's mantra -- know your tartan!

BTW, Todd, when I wrote the e-mail I went into a little bit of detail regarding my McKnight ancestors, and explained a paragraph or so about what I'd learned regarding the Ulster McKnights/McNaughtons...
How James I knighted the clan chief of the MacNaughtons, and that his son took the name "MacKnight"...how a number of MacKnights and MacNaughtons moved to Ireland after the British put down the Irish rebellion of 1607 and so on. I explained the relationship between my ancestors, James McKnight and John McKnight and the Masons Lodge of Alexandria (George Washingtons Masonic Lodge), and their American Revolutionary War involvement. In other words, I made an effort to show that I'd learned something about the clan, it's history and it's traditions and it's role in the history of the USA.

Like Jimmy says; "know your tartan" which might mean "know your clan and it's history". This is not "work" it's FUN! Anyway, that was my approach and my impression was that it was appreciated by the Clan Chairman.
