We gave DD1 a very unusual name - a historical and classical one - but very unusual! We didn't tell a soul during pregnancy as no one I know likes the same name styles we do and I didn't want any criticism. I told one or two people who I knew loved the same sort of things we did!
We then had a bit of a disaster during the pregnancy and during that awful time I decided to tell my family our chosen name (incase we lost the baby - happily we didn't). I was a bit calculating as I knew full well they couldn't say anything awful about her name when we were under such a risk of losing her!
I have absolutely NO regrets about my name choice and I love it to bits. I would use it all over again if I could! I've not been met with any overtly negative comments at all since she was born- which in a way I find a little disappointing
I'm always up for defending it!
However, my father dearest did say to me that at the time he felt that her name was going to be more of a difficulty than the disability that she has! That hurt like hell. I reminded him of what he said last week, and he was utterly mortified and apologetic!
In my experience, people don't question your choices so much once the baby is there. That name simply becomes their identity, no matter how unusual. However, I will certainly NOT be telling anyone our name plans for baby number two (unless - heaven forbid - we have a similar awful experience!) and I cannot wait to announce it in 8 months time 
My advice is stick to you gut and don't tell anyone about it - they'll only put you off and so many people can be a little put off or frightened by unusual names!
(They're going to be bullied... my ass!)
