I was thinking about this, but it might not make sense:

So to put it in short Sokka married Suki, had two kids Tonraq and Unaloq, then Tonraq married Senna and had Korra, while Unaloq inherited the position of chief, married Malina and had two kids Desna and Eska.

But here's the problem: Sokka wasn't a chief, he was a council member in Republic City...?

What do you guys think?
