My 2 DD's don't have usual names (Brittany & Rebecca). And really neither do my boys- UNLESS you really think about them.
Oldest is Ryan Mackenzie- after an old soap Another WOrld- lead character Mackenzie Corey & his son Ryan.
4th child (2nd DS) is named Logan Scott- after Wolverine & Cyclops from The X-Men.
5th child- Shawn Angelus- Angelus being after Angel from Buffy the Vampire Slayer!
