They are multiplying

[Felis]

Now... I know nothing about the lore, so I won't claim any knowledge. but a friend of a friend of a friend told me a while back that Miqo'te are named according to the tribe? or... Something like that? Not so much related, but possibly connected somewhere back?

Again, just a shot in the dark. Mayhaps I should research before commenting? ah well, I'll be corrected, I'm sure

That are the Seekers of the Sun.
The first letter is the tribe and the surname is the name of the father.
example: Y'shtola = Shtola from the jaguar tribe (short Yah)

Unlike the Seekers of the Sun, the Keepers of the Moon is a highly matriarchal society, with family names passed down from the mother, not the father. It is said that some of these surnames have survived since the First Astral Era.

So the Keeper of the Moon surnames are more something like clan names
