I remeber from reading the player's guide that there is only 1 Argonian woman who you can marry (and only two argonian men). I'll check the list later and let you know who it is.
Be glad you didn't play as a Bosmer or Khajiit, because these two races don't have any marriage canidates at all. The good news is you can marry any marriage canidate, even ones who are not the same race as your character.
