Naming Help!

Currently 34+ wks and on "team green," so we need a girl's name and a boy's name. We thought we had perfect names picked out (Isla and Graham) but my brother and his wife plan to use those for their baby and it's not worth the drama. We love old fashioned unique names (ex: Willa, Hattie, Arlo, Harrison) and don't want our baby to be one of 4 kids in their class with the same name. Every name list I come across says "you've never heard before" but they're all the same. 
Can anyone suggest some good names we may not have heard or considered??
