Currently none are confirmed. Hopefully we'll have an answer soon though.
I don't buy into this Sokka is Lin's Father thing. If they were true, why keep it a secret? Why not have Sokka on the officially released family tree next to Toph?
Because that's such a scandalous thing and creates the theories that people oh so love. Sokka at the end of the show was with Suki, but what's this? A child of Tophs that doesn't look like Toph??? It can almost be compared to the Zukos mom bit of "WHERE WHAT" type of thing. Many people shipped Sokka and Toph, and the idea that the two got together after a falling out with Suki makes it rather... real. Since that happens.
There's more to the story that they're hiding for now, and the fact that Tophs husband is a complete mystery that is just a huge step in what since in the family tree released it had Korras parents names. Them creators are crafty like that, in fact there was little information of Asami till she appeared, so it's obvious that they're holding back information to create interesting reactions. They're being brilliantly crafty with how they're releasing information on Korra. Never seen this in such a long time since it makes theories and conversations. <w<
I think we need to slow down some.
1) I think Linn looks plenty like Toph.
2) I mean...I'd feel rather cheated if they broke up our canon off screen, and then paired up other characters we already knew.
3)I think it's just as possible that Toph ya know....met someone after she turned 13.
