From the experts:
The name Barney is hot among hip Londoners and it has been above the Top 500 in the UK since 2012. You can see why - it's got a friendly happy sound and a lovely meaning and is more easily worn than Barnabas. However, Barney is a more difficult sell in America, due to Barney the Dinosaur and Barney Gumble, the loveable lout from The Simpsons. In the positive column for Barney are jazz clarinetist Barney Bigard and guitarist Barney Kessel. For those who love the name but can't get past the dinosaur, may we suggest the related names Bernard or Barnaby?
