Ailan and Mabreka are their first names (or given names if you prefer), we know that much.
All current leaders seem to go by their first names. Though the previous Tryker governor went by last name, he was named Still Wyler and went by Governor Wyler, not Governor Still.
For wandering NPCs however, it's anyone's guess :P
It's funny though, all Tryker NPCs have a ' in either their first or last name, but never neither and never both. All Zoraï NPCs have a - in either their first or last name, but never neither and never both.
