Haha, I think it's legitimately ignorable. If you dig through Tamora Pierce website, apparently she's given names and spouses to a lot of characters/kids, like Wyldon's daughters. And Kalasin and Kaddar's son. And endless minor characters who were never more than mentioned, like Neal's little sister.
It's like the big interview thing JK Rowling did after the Harry Potter books where she talked about who married who and had kids with who, and what their careers were like, etc. Frustrating sometimes because as much as you want to know these things, it rarely aligns with your own imagining of these futures.
