Theory #1 and #3 of Reli plus a new one.

I noticed in Cobra's fight with Natsu that when the Exceeds carry the Dragon Slayers, from a distance they look like Fairies (from the Exceeds' wings) with tails. So I was wondering, maybe, just maybe Fairy Tail used to be a Dragon Slayer-only guild in the far past, and that is what it took its name from. Maybe Mavis chose that name for something dragon slayer-relevant.
