My understanding is that the sept (indicated by name) would wear the tartan of the clan to which they had allegiance - based usually by in whose lands they lived.

(Of course there is the inevitable digression about "official" clan/tartan affiliation before The Clearances and King George's visit.)

Since then through research, I've discovered that the Gaelic form of Gray is MacGashan. MacGashan is a Sept of the Clan Stewart - Stewarts of Atholl. These Stewarts are a branch of the Royal Stewarts.

Any comments?
With respect, it seems as if you may have all ready answered your own question.
It seems like you have been able to develop a reasonable justification to wear that particular tartan.

But if I may play devil's advocate for a moment, is your desire to wear this tartan to pay respect to the MacGashan branch, or is it that you have found a tartan you would like to wear, and have developed a justification for doing so?

Neither choice is wrong, of course and I mean no disrespect by asking.
