There's not a ton of canon lore on the individual Seeker tribes (except the U) because while all the Seeker tribes are similar in general, each individual tribe and the many splintered sects of those tribes are all different. What I can give you are a couple relevant links to some info on the tribes in general:
-Race Lore Compilation (Miqo'te)
-Seeker Tribe Distribution (2.3)
Hope this helps!
