Never knew that!
You can read in the foreword to George MacDonald Fraser's wonderful history of the border reivers, The Steel Bonnets, how he got a jolt of recognition at Nixon's inauguration seeing Lyndon Johnson, Richard Nixon, and Billy Graham all side by side. Not only are all three names Border names and still very common there, but each of the men's faces was a recognizable Border type that you can see anytime in Carlisle or Jedburgh - the big rawboned, bulbous-nosed Johnson, the leonine Graham, the wee dark fierce-browed Nixon.
