A) The feminine forms:
Robin,
Robyn,
Davena (sorry, that's close), Dava,
Jaime, and ... how about
Marsha? Or maybe Marshella (Marsh-elle-ah)?
B)
Robin. Sorry, I know I already mentioned that for a girl's name. Other than that, I can't think of anything, except for maybe
Jacob which I doubt you'll like because it is so high on the popularity charts. (I say
Jacob because
James is supposedly an Anglicized form of
Jacob.)
C) I don't really wish to give away my own choices for two of those names (
Marshall and
James) because they are actually on
my list. However, I'll give some off-the-top-of-my-head combos.
Andrew JamesCedric JamesCaleb James (not my own; my handbell director's neice named her son Kalib
James)
Daniel JamesAlexander DavidGraham David (not my best combo)
Albus
David (sorry, just had to slip some
Harry Potter in)
Henry David (Henry=Harry=can't get HP out of mind now)
Adrian MarshallStephen MarshallAshton JamesRobert Sebastian (sorry, it's just so hard to pair
Robert with anything, especially as a MN)
Peter Robert (not my best)
I tried. =)
