I just want to interject with a brief statement; and that is that generally speaking there is no such thing as a "right" or an "entitlement" to wear a particular tartan.

The choice of what tartan to wear is a personal one. Tartans are used today to symbolize all manner of things from clans and families, to regions and jobs. It is assumed that when you wear a tartan you have some sort of connection to whatever that tartan represents. Whether that connection is the actual surname you bear or the name of a great-grandparent, that's nobodies business but your own.

I met a man once who wore a kilt in the Cameron tartan because his dear friend, who was active in the Clan Cameron Society, had died and bequeathed the kilt to him. He wore the kilt in honor of his departed friend, despite the fact that he had no connection to the clan. The tartan meant something very dear and personal to him.

It is a fact that when you wear the kilt, people will ask you about the tartan. You should be prepared to give some explanation as to why you wear the particular tartan you do. If you are satisfied with the tartan you have chosen, that should be enough.

Again, there is no such thing as a "right" or "entitlement" to a tartan, with very few exceptions which the general public need not be that concerned about (as I mentioned in an earlier post).
