awww come on!

even if they did have kids, they would have only been, like, little bitty when their parents were taken to Azkaban.
I don't think they do, though, or at least, I don't think they have kids at Hogwarts. Remember after Harry gave the interview, and he named all those Death Eaters, and they finally got arrested, the children of the Death Eaters arrested were Malfoy, Crabbe, Goyle, and a guy we've never really seen before (except perhaps when he's sorted, I can't remember) called Nott (or Notts, can't remember). I think, at that time, we would have seen the Lestrange kid hanging out with that group.
If they did have children, and they were at Hogwarts, I don't think either them or the other students know that their parents are the Lestranges (as in, it all happened when they were very young, and they have different last names now). We don't ever hear of Neville having issues with the Lestrange kid, and I feel like it would at least be mentioned, sometime during the GoF and OotP.
