Naturally, I'd have to agree with the idea that there is always rooms for exceptions so long as it's noted in some way, shape, or form -- even if that reason isn't ever explored ICly for whatever reason. I ran into this issue myself, as I played a Hyur during 1.0, and my character's name was quite Hyur. I had, however, always wanted to be Miqo'te from the get-go, and I took the chance when it rose up.
As opposed to changing my character's name entirely, he simply became a non-tribal Miqo'te. This was even easier for me, as my character was born on Ilsabard to begin with, not Aldenard. We do know that not all tribes settled on Aldenard. The ones that did are the ones we know canonically, but there are supposedly others that wandered to various regions. Plus there are likely those that never made the migration (which my bet is on them being the natives of Meracydia.)
At some point, Merri's ancenstors removed themselves from a tribal life in favor of a life in the (then) republic of Garlemald. He was obviously born after the Imperial regime had been instated, and let while young for reasons.
