On a side note, MacBubba is ACTUALLY recognized as an "official" clan society by Lord Lyon (who I THINK is a member himself, I know one of the two official hearaldy artist is). It is NOT an official clan however, because part of the Scottish legal definition would require the geneolgical connection between the "clan" and a man name Bubba or MacBubba who lived in Scotland, yada, yada, yada.

As you can tell, I have NO problem with a "non-Scottish" kilted clan.
I have also toyed with the idea of a Carolina "clan" named MacArolin
Clan tartan-> Carolina
Crest-> coiled snake (on yellow when in color) with the slogan "Calca Non Meum" (Tread not upon me)
(Obviously based on the American Revolution flag that was designed in South Carolina and heavly used during the southern campaign. Ot was also used elsewhere, but is often associated with South Carolina particularly and the Carolinas in general. It was also the ensign of the commander of the Revolutionary Navy)

From the Carolina colony,
