Different save of CK2/AGoT mod, same Crowned Stag bookmark.
State of Westeros as of 320 AC:
Still sitting the Iron Throne is Robert "Bobby B" Baratheon, now 57. Last major campaign (conquering the Stepstones) completed, now in a holding pattern until my death. Son's possibly gonna deal with a White Walker invasion.
Bobby B's children and descendants by {Cersei Lannister}:
-Steffon, Lord of Rosby and current heir, 31. Married {Margaery Tyrell}, m. Tyalla Manderly
(no children by Margaery)
(by Tyalla)
---Eleanor, 6
---Kyle, 3
---Ammina, 1
-{Byron}, tragically killed by Ser Mandon Moore of the Kingsguard during their joust at the Tourney of Duskendale in 316 AC at the age of 25. Married to his half-aunt Leila Lannister
---Marena, 10, current Lady of Dragonstone
---Lysanne, 6
-Andrew, 24, sworn brother of the Kingsguard
-Sarella, twin to Andrew, m. {Brandon Stark}, m. Robin Ruttiger, Lord of the Western Stepstones
---Josmyn Hill, 5, her baseborn son by Eldrick Sarsfield
(by Robin)
---Jonos, 3
---Leslyn, 2
---Aleyne Hill, newborn, baseborn daughter also by Eldrick Sarsfield
Summary of the first four kids: Steffon's becoming a drunk sex maniac like his father was in his youth; Byron was a talented-enough kid; Andrew was a competent-enough swordsman and got him out of succession; Sarella is, despite being something of a lackwit, somehow talented at making people not like her. Highest profile rival of hers is Meera Reed.
==========
His children and descendants by his current Queen Myranda Royce:
-Boremund, Lord of Torturer's Deep, 22. Married to Alarra Forrester
---Ronnal, 3
---Maris, 1
-{Maris}, lived a single day in 301 AC
-Arya, 17, given to the Faith of the Seven and now a silent sister
-Stannis, 12
Summary: Boremund annoyed me so got him out of the way, Arya made it 2/2 on surviving lackwit daughters, figuring out what to do with Stannis
==========
(Confirmed) Baseborn children:
{Valarr Waters}, his son by {Daenerys Targaryen}, died under suspicious circumstances at the age of 19. Former Lord Paramount of the Stepstones, founder of the Baratheon cadet dynasty House Stormhart. Married to Annara Morrigen
--Sebastion, 1, current Lord Paramount of the Stepstones
Backstory: RP'ed this with Bobby B wanting to deal with the last two Targaryens. Kidnapped both Viserys and Dany. Viserys was useless and so executed by drowning in a vat of wine in 290 AC at the age of 14. Dany was executed by strangulation in 300 AC, three days after Valarr's birth. Valarr would, nineteen years later, ironically die on the same exact day of the calendar.
Beatrice Hill, newborn, by Deona Vikary
Backstory: None, this was for giggles.
They are the only two confirmed ones. Thanks to the magic of console commands, I know that he had at least two more: Rosalind Sarsfield (by Meera Reed) and Lady Paramount Alyssa Arryn (by Gwenna Arryn).
