My DS2 (nearly 10 months) is Wilfred, known as Wilf or Wilfie (at the moment but if he wants Wil when he is 16 then fine.) OP, it never occurred to me for a second that he would be bullied for his name, but then we live in London where I think just because of its international nature, different names are not such a focus. DS1 is at pre-school and his friends are called Otto, Polly, Xanthe, Loveday, Caspar, Solomon, Cosmo etc. Nobody bats an eye.
Personally I think there is more pressure to "fit in" in a smaller, possibly less cosmopolitan environment...if the classrooms are populated by Sophies/ Thomases/ Emilys (no offence,all lovely names, I am just giving an example)then a kid called Lucretia or Willoughby may sound a bit left-of-centre and be a focus for torment?
I went to school with a girl called Barbara which seemed ludicrous in the 80's when everyone else was called Sarah, Clare and Rachel, but it was funny for 5 minutes and that was that.
If you like a name then go for it... people get used to it sooner or later and it really does become irrelevant
