In Southern Salenzis, there would probably be mostly incomplete stem and communitarian families, especially in Igion. Egalitarian nuclear would probably be a rather small minority in Igion, becoming a larger one as you go eastward - through Gallar, Upper and Lower Jilneas, Giel, and Antiem - towards Zarcos. Zarcos would then probably mostly be both types of nuclear, with pockets of communitarian here and there in rural areas. Ticondera, west of Igion, with its Jamic cultural substrate, would probably be much more stem than communitarian. Propha would probably also be heavily stem.
Across the Vast Ocean to the west of Salenzis, Shorrag's family types would be heavily dependent on what region you're in. The hunter-pastoralists of the central savannah are definitely communitarian. The highly competitive coastal region (don't refer to them as one region to their faces) would probably be nuclear of some variety. The uplands are probably where lines of descent matter most, so stem. The Badlands, to the west of Shorrag, while not technically part of Shorrag, has a Shorragite population - mostly miners and soldiers. It's a sparse population, though, being in a desert, so I'd say that some kind of nuclear probably prevails.
