Jumping into this thread a bit late I'm afraid but finding it really interesting as am pg with DC2 and thinking a lot about old english / celtic names for the same reason as sushistar. I wanted Merlin for DS but DH vetoed it (I'd have loved Taliesin too but didn't even bother suggesting it, would have been laughed out of the house!) so we agreed on Arthur instead, which people always comment on as being lovely, unusual but not too out there (apart from MIL who said 'poor child'.)
I know quite a few people who are known by their middle names, and don't necessarily have weird and wonderful first names - they just don't like them.
Perhaps a sensible suggestion to cover all bases, Sushistar, would be to give your next DC names that you absolutely love but with a middle name that is slightly more 'normal' in case they want to change to that should they experience what Seeker's brother's stepson has experienced?
To put in my two pennorth though, I love Rowan, Malachi and Eldred.
I have to say, Sushistar, good on you for choosing names you love and get excited about - there are far too many Jacks and Sophies in the world if you ask me. Actually, one point about the bullying aspect of names is that when you get lots of kids in one class with the same name, they tend to be differentiated by size / shape / appearance, so they become 'Big Lauren' or 'Fat Chloe' or 'Lanky Lucy' or whatever, which is just as horrible for the child as being teased for being called Taliesin or Thor.
BTW I have a slightly unusual name that no-one can ever spell correctly, and I don't mind spelling it out all the time. You get used to it after a while!
