Thanks again to Silvercyclops, I'm starting to really like the idea of Shalla as a partner for Kell in a Tyrilynn timeline, and I'm thinking again about the kids.
This fic from a month ago mentions Jesmin as their baby and it got me thinking about how I think the kid situation should work out.
In his one direct appearance in canon that I can remember, Doran Sarkin-Tainer is basically Mini-Kell But A Jedi. He probably doesn't exist as one of Tyria's kids if Tyria is with someone else, but he can still exist in a recognizable capacity as Kell's kid if Kell is with someone else.
So as far as my current headcanon goes, Doran Nelprin-Tainer and Kithara "Grinder" Sarkin-Sandskimmer - the first Tyrilynn kid, who for our current purposes is sufficient to summarize as Mini-Falynn But A Jedi - are in an approximate age group with the YJK generation, and Jesmin Sarkin-Sandskimmer is Tyria and Falynn's second daughter, born in 19 ABY.
