Lots of questions...

As posted above, name is not the only criteria. Where YOUR family lived in
Scotland is the key. The Comyn name was banned in the fallout of a dispute
over succession to the crown. The Lendrum name is a place name adopted by one of the most directly affected sons. Others followed suit, reasons could vary by family. It is said that most with the name in this country can be traced to two brothers who came to VA from Scotland.

Have sent a PM which may or may not be relevant to your situation. Only
your genealogy can make a definitive statement. In this country, wear what you choose, join the clan society or not, or petition the clan chief directly.
If none, you're on your own. I did not see your name on the "accepted"
names list, nor is it on the list used by the Clan Cumming Society of the US.
The clan appears to be armigerous.

The Tartan Police will not appear at your door, they being in bit of a bind with Homeland Security over statements taken out of context to be terroristic in nature, and by the time that's resolved you'll have your genealogy well in hand. In the meantime, wear what your heart calls you to,
being prepared to have discussions with those of an officious nature.
Wear it well, with respect,wiyh knowledge of the tartan, with joy, and with a good story about how it came be your choice. Do take a look at the Society page.

HAVE FUN!!

Thanks alot for the info, guys. Ha, yes, I know that the tartan police will not show up-I'm not worried about breaking any rules or anything, I'd just like to wear a tartan that means something about who I am and who my family is/was. I wear a Scottish National tartan right now and have worn Irish National and Black watch tartans before, I'd just like to have something personal for family occasions and things like that.

How would I go about petitioning the chief? Since there is a Lendrum tartan that I plan on purchasing in the near future, my question is less about what tartan I should wear and more about what clan I would fall under.

Thanks

Having just done a quick google on your surname it appears a lot of your tribe came from the Turriff area of Scotland (source Stacy Landrums page) If you can trace your scottish roots to that area it might give you some joy.

As to it being the name taken by Robert's adversary to the throne after they were done in, a bit more research maybe required.
