User blog:Wings of the Wind/Name Trouble

Every time I think I've finished creating all character pages, a new character seems to sprout up. I'm facing quite a dillemma with the recent ones. Is it Gray or Glay? Somewhere I read it's written Glay while another place indicates it as Gray. Another troublemaker is Van. Is his lastname Argeno or Argiano? Was it Grigory or Gregory? Btw are the twins (Diva's daughters) named? I'm totally confused...If anyone have any opinion or knowledge as to what's the correct one, please share it.
