They are multiplying

[Eloah]

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

You aren't entirely wrong, Seekers of the Sun Mi'qote have tribes A-Z like Y'shtola & Y'mhitra. But since Seekers are Patriarchal, the majority of the tribe is inter-related. There is a breeding male, who mates and produces children, until the next male is "selected". Males will always be either a Nuhn (breeding male) or a Tia (non-breeding male) and any female offspring will bear the name of their father as their last name. In this case Y'mhitra and Y'shtolas father was, Y'rhul. Now based on the lore book we have an idea about these tribes. First Y'mhitra is older than Y'shtola by 3 years, or that is the way it seems based on their lore book entries, and Y'mhitra'e entry says she is 7th of 12 sisters. Now this could either mean that Y'rhul sired 12 offspring while he was a nuhn, or one Mi'qote mother had 12 daughter by him, which isn't impossible. But, I would believe the former since raising a child is tough and to be in pique "condition" for having a child, you'd have to have the them back to back at a young age. but anyway. Say Y'rhul did have one son, before he stepped down and another Nuhn was choosen. Now the new nuhn might have 16 children with the Rhul sisters. then when the time comes, Y'rhuls son is choosen as the next nuhn and has 13 children with the daughters of the original Rhul sisters, his sisters. See where I am going with this, each tribe by itself is interconnected in its relationships, and will remain so until someone either breaks away for whatever reason, or someone is brought in.

Now as for Keepers, those families are a bit different, namely they mimic the structure we would view as normal, Mom, Dad, siblings, they don't have tribes only a nuclear family. Now similarly, people who have your last name may be related to you, or may not. It's the same with Keepers, their last names might be similar and they have no familial relation, or they are cousins distant or otherwise. As for Zhloe and Khloe, we know they are sisters, but as for Leih that is up for debate.

The weird thing is that the Mi'qitten that lost her parents in Idyllshire is a Seeker, so her having a "father" is a little odd, given the structure of their tribes. Even if he stepped down as a Nuhn, wouldn't he have other children? The only other possibility I could see is, if wasn't a breeding male, and him and his wife running away since they "had a child" not under the proper rules of their tribe. The fact that they "were" in Idyllshire might support this as I believe it is unlawful for a male to breed if he is not a nuhn.
