Macabre names?

Alexandria
My boyfriend and I are kind of a little macabre. We enjoy making light of dark situations, very mortician and Gomez. We've decided the if we have a boy his name will be Leviathan Casper Warner but we're having trouble deciding on a girl name that's dark in meaning but still wearable. If we somehow manage to have a girl on a Wednesday well name her Wednesday Ophelia Warner but we're hoping to go natural so that's a shot in the dark, any ideas??
