I'd actually prefer Lauren Larkin, but that's me :-)
My *ONLY* problem with this is that then she'd be identified with a different side of the family... Like, this isn't my grandmother's LN, so it's not my dad's LN and in turn isn't my maiden name. So, while I wanted to give a nod in that direction, I don't want to make her part of that family so to speak. I know this sounds contradictory to what I'm trying to do, but it makes sense in my head...
I'd rather give her my maiden name as a MN than use the full Larkin.
I agree that it sounds good, but that's my reservation on that issue.
