Do a search for the name McDonald's in Scotland. There is a lord of the clan McDonald, who's pretty peved at the McDonald's corporation. According to Scottish tradition, using the name of a clan requires the permission of the head of the clan. McDonald's Corp hasn't asked permission of clan McDonald to use the name, and they are suing several small companies in Scotland (some of whom have been in buisiness since before the founding of the United States) over "stealing" their name.
