I actually wanted Romilly Poppet on the bc but DH vetoed - but she gets called that anyway (mostly by DH, weirdly).
I think EldritchCleavage is right - Romney does have a romantic quality to it.
I think you should go for it - try to imagine how you'd feel if you didn't use it. Would you always feel that pang of regret if you went for something more mainstream?
We got lots of
faces when we divulged the name beofre Romilly was born (SH's family are used to Lucy, Emma, Emily type names). I'm really glad we took no notice.
