I wouldn't say my first name is THAT rare. Robert is a good traditional Scottish name. And so is Ewing, that's rare in the sense of how it is written, but not in the sense that it's had many, many turns of evolution. Ewing can be traced back as, Owen, Ewin, Eugene, Oewynn. Loads. Not sure what Ewing means, I know in some places it's known as a forest, but not in Scotland.
