Willamina or
Willa, or even Shenandoah?! That would be a kick-butt name.
I'm not seeing the connection between Shenandoah "Shenan" and Shanley myself. Even
Shannon seems more connected to the actual name than Shanley.
BUT regardless:

PS - I started writing "Shanely" by mistake after a bit - what about that? Seems a touch more girly :)
