(as the Vale has excluded women from succession for a while, the current heir presumptive is Joffrey's brother Artys)
==========The Iron Islands==========
REGNAR BLACKTYDE, 20, m. Gwynesse Blacktyde (common great-great-grandmother, so....er, third cousins (?) so very normal in-universe)
(no children at the moment, also male-only succession, so Regnar's brother Gormond is heir presumptive)

--ANNET, 12
--JEFFORY, 7
-MYRIA, aunt to Axel I, 30, m. Luthor Flowers (baseborn first cousin, as if I need
more reasons to hate the Tyrell family tree at the moment.*)
--WALYS, 3
(by Kellyn)
-MORYN, newborn
*baseborn daughter of Ormond Prester and Isla Baratheon. Head is hurting here: Teddy Tyrell is my first cousin. Kellyn Prester, despite being a scant two years older than Teddy T, is his grandmother-by-law. Her cousin is Teddy's wife. Orena, meanwhile, is a second cousin of mine via our great-grandfather Ronnal I Baratheon. Gareth, meanwhile, is a grandson of Bobby B himself, who is my great-great-great-grandfather. Gods what a stupid family tree.

-RELLA, heir, 9
==========Dorne==========
OLYVAR MARTELL, 20. "Unwed"
(no kids, which I will explain soon why. Heir at the moment is Olyvar's sister Mara)
" "=My headcanon is calling it unwed.
TL;DR=In-mod, marriages can get wonky when the bride is also a younger ruler. Get wonkier still when dealing with people who go full-Targaryen but that's a tale ofr another time. Saying this because the mod had him married married to Mylana Farman...who was 11, supposedly too young for anything beyond a betrothal without console commands. Not that there isn't precedent for this in the ASOIAF series, just terrible implications when viewed through modern eyes. Console-command shenanigans happened by killing off Mylana and subsequent plugging my ears and humming
very loudly when confronted with this.
