How about Di? Then her name becomes Di
Ann (
Diana was the goddess of the hunt and of the moon in Greek mythology). It's better than my idea of
Isis (
Isis Ann just seems to grate, ykwim?) or Pele
Ann (Pele is the Hawaiian Polonesian goddess of fire. Again, the combo seems to grate, in my opinion).
Phyllis (aka Sidhe Uaine or
Gaia Euphoria)
