For a girl, we had chosen Nyssa Rose. Nyssa was Doctor Who's companion in late 70's/early 80's. Rose was Doctor Who's companion in '05/'06. Sad isn't it?
Not sad! DH has decided that if we are having a boy, he is going to be Ianto Jack! The only reason we haven't gone for a Doctor Who name for a girl is that I don't like the old series, DH hated Rose (the character), and neither of us like the names Martha or Donna. So you're not sad at all, you know what you like

PS - Jack was chosen as a middle name long before the decision was made about Ianto being the first - It wasn't even chosen because of Torchwood, just a happy coincidence.
