Katharine nn Keats would strike me as really cool, but I'm much more partial to
Kitty as a nickname, personally. :)
Makeda's another option, but that's...trendy. Even if it's historical. :/
Keturah's a stretch, but it
could work.
Keitha and
Keithia, the same.
Keats seems like the best option, since
Keaton's much too masculine to my ears; all I hear is
Buster Keaton (not a bad thing, but not the image I want when I think of a name for a girl, personally). And I think Keats could grow on me--it sounds like someone I might meet at my all-women liberal arts college. ;)
I don't find your list too mis-matched at all. They all strike me as being nicely out of the mainstream; to me, they've got this image of being
actually rather counter-culture-bohemian instead of poseur. You know, the stuff that all those little Scarlets seem to be yearning for. DIY and
Buddy Holly glasses without being pretentiously look-at-me! about it.
Array (who is stuck with yearning-for-boho
Scarlet Carson, lol)
I want to be be more like a river--
Less like a wall--
Not trying to hold back these feelings at all.
A revolution without dancing is a revolution not worth having.
