"And Benita knew this ring as well as she knew her own fingers, having heard a long history about it; and the effigy on it of the wild cat was the bearing of the house of Lorne"

Lord Lorne is a title in the Peerage of Scotland.  It was first created for Robert Stewart, son of John Stewart, ambassador to the English King, in the early 1400s.  Prior to this, the Mormaerdom, or Kingdom of Lorne, was a lordship in High Medieval Scotland.
