I wouldn't go for Ophelia, despite loving it, because it sounds too much like "I'll feel ya."

I did have Jareth on the name list for DS, after David Bowie's Goblin King in Labyrinth. And I suggested if our fourth child was a boy, we could call him Ivor. But with a Welsh accent (I'd been watching Ivor the Engine) so it would be eye-four, and he'd be the fourth child... but DH had already freaked out about more children, let alone three more by then. And I'd already named a computer i4 before after Ivor the Engine.

Oh yes, with the Dr Who link, I suggested Brigadier for DS too.
