They're set as her kids, I just had to assume that they were all Coryn's kids. If you click on characters, it opens up more of the tree. Clicking Jack has Raze and Onna set as his kids (only way to "foster" onna into the family. I left a note on it explaining that she was adopted into the family by Jack) and clicking Gray brings up Stardust. That's the best I could do.
All of Kei's stuff is noted on his character profile. He has no kids and ended up working with The Jedi Order after a three year exile.
