As a self-described American mongrel I have been doing some work on my genealogy and it seems that my ancestors came to America from England, Ireland, Wales, and apparently from Scotland. The Scottish roots are from the Sanders who according to the websites I've seen are a Sept of Clan MacDonnell (of Glengarry) and emigrated to South Carolina in the 1700s. Is there any permission needed to wear the MacDonnell tartan? Also, the Sanders connection is 4 generations back, is that too far back to claim any affiliation? I know there are no such thing as "kilt cops", but I want to honor the traditions of my forefathers, and not behave in a manner that shows a lack of respect for them or for current members of the Clan MacDonnell.
