I live in Australia which has similar naming trends to England.
I know 4
Barney's. 2 Bernards (One is 35 and one is 1) and 2
Barnaby's (1 in 30's one in teens). One of the Bernards was my music teacher and I always used to tease him about the purple dinosaur, once we filled his class room with them! But it was an affectionate thing and he didn't mind it. The others never get the whole 'purple dinosaur thing' and no one really caught on with
Barney from the simpsons. THe
Barnaby's i know go only by
Barnaby and I think
Barnaby is so handsome.
Barnabas is nice but slightly stuffy.
Go with it! Be different! Who knows maybe they will get rid of the dinosaur
