It's funny how your liking of a name is influenced by people you know. On any given name thread, someone will always pipe up, 'I was bullied by a Gemma/Mandy/Annabel at school so I hate that name now', but it's rarer that people say 'God, that's an objectively horrible name, but I know a fabulous Gertrude so I actually really like it now'.
I don't go in much for Irish names usually, but I make an exception for Siobhán. I've never met a nasty one. All the Siobháns I've ever come across have been really sunny and lovely.
However all (ok, most) of the Joshuas I've met are a different matter.
