District Tartans that I have an association with, and would like to wear:

Argyll
Buchan*
Aberdeen
Huntly District
Glen Orchy (the Cumming Tartan is very similar)
Clergy (I am a lay eucharistic minister & sub-deacon in the Episcopal Church)
Fife
Roxburgh
Galloway (Red)
Northumberland/Shepherd's Tartan (Wilkinson is a Border name from Northumberland)
Burns Check (World Burns Federation tartan)
Scottish Knights Templar
Ulster (Red)
Co. Dublin (one of my Scottish ancestors moved to Dublin & worked as a tailor)
Nova Scotia (for my wife)
Ontario (Ensign)
Louisiana (for my wife)

* My Cumming Hunting (Old Colours) kilt is also the Buchan District Tartan.

I also like:

Stewart Hunting
Caledonia
Culloden
Lady Borrodale's Gift (to Prince Charles Edward Stewart)
Tara

That's all I can think of for now, but there is more...

Recently I joined the Scottish District Families Assocation (SDFA)...it is for people with Scottish ancestors who were not part of one of the "big" clans and whose name is associated with a District Tartan --their web site is http://www.scottishdistricts.org, in case anyone is interested.

The Scottish Tartans Museum in Franklin, North Carolina also has a new web site, www.district-tartans.com, which is very good to peruse and anything that the STM is good in general -- their curator, Matt Newsome, knows his stuff!

Cheers,

T.
