What if -and I realize this is very farfetched but it seems kind of plausible given physical features - Zuko is Lin's father, and Sokka is Suyin's father. It sounds farfetched because Zuko wasn't all that interested in Toph or even at all, but look at it like this: we don't know who Izumi's mother is either because for some reason Zuko and Mai didn't end up together. So look at Lin's physical features (when she was younger): black hair (both parents), sharper eyes (as opposed to Toph's kinder, slightly down-turned ones), the perpetual frown (Zuko, though this could just be a behavioral thing, but again, Zuko). Also, Lin's eyebrows look like a combination between Zuko's and Toph's. This seems like grasping at straws though because Toph and Zuko weren't all that close, also we don't know how long Zuko and Mai's relationship lasted and implications of an affair would've been mentioned in the series. A one-night-stand is possible, however, but again the issue of why Toph didn't want to tell him pops up.
Now, Sokka as Suyin's father seems very plausible. Her dark skin very much so implies Water Tribe lineage or at least dark-skinned Earth Kingdom lineage. Suyin's habit of collecting meteorites is very much like Sokka, or possibly Toph found it interesting and passed it on to her. Also, Suyin's male children have a lot of Sokka's features, like his facial shape and hairstyle, especially Bataar Jr. They have very similar mannerisms. This again seems farfetched for many of the same reasons that Zuko X Toph does; what happened to Suki? When did their relationship end? A one-night-stand is possible but why wouldn't she tell him given their close relationship?

Now that you mentioned i still wonder whos Lin father and what happened to Soka with Suki.
Some mentioned Sokka broke up with suki and from the Family tree Sokka doesnt even marry someone.
Meanwhile my assumption were Sokka married both Suki and Toph but disclosed and never explained in story.
You mentioned that Suyin have similiar physical trait from Sokka and personality wise she and her children does resemble Sokka.
At least thats what i wanted to believe

Sokka is not the father.
Toph said herself that Lin's father was a guy named kanto. I belive that Toph had a arranged marriage with Kanto and didn't really love him, so she probally left him bfore having Lin . I belive Su's father is Haru and Toph truly loved him but out of jelousnes kanto killed him bfore Su was born
I believe that Sokka had a son with Suki, who happens to be married to Suyin.
i agree baatar Sr is probally Suki and Sokka's son
{My theory} Baatar is Suki and Sokka's son and Suyin father is Satoru he was a darker earth kingdom civilian very technological and has similar hairstyle to Suyin as well as Toph and Satoru had a crush on eachother in the comics.
Lins father is a man named Kanto.
