Sorry about your earlier loss Curval, but congrats on the expected new arrival.
Having seen the original Dr. Zhivago and the new Masterpiece Theater remake, and having concluded that Julie Christie and Keira Knightley are two of the hottest females who ever walked the planet, may I suggest: Larissa
Advantages: Comes with the ready-made nickname of Lara, plus a really cool theme song for love-sick boyfriends to tip orchestras to play.
Disadvantages: distinctly Eastern European (if your last name is Corleone or O'Toole, it might be a little awkward, particularly with the balalaika music)
Anyway, enjoy upcoming fatherhood!
