StatueInTheSky,
That sign's brilliant! 
OP,
I'm undecided about Hugo. I like the name itself, esp the meaning "mind, heart and spirit", and it works internationally.
I know one adult Hugo (late 30s), who is about as far from the stereotype as it's possible to be, and has the sharpest sense of humour ever. Have occasionally come across the 'old money/ family connections/ traditional' kind of Hugo, but wouldn't pre-judge before getting to know them better.
No little Hugos around here, but several Hughs.
