No one. Turns out this version of Miles dedicated himself so much to heroics that he never actually started a family. But Ganke's daughter starts to mention that she thought he should've ended up with Kamala, but Miles changes the subject.
It was an okay one-shot. Not much of an explanation is given for how the world ended up the way it did, but I thought it was okay overall. It's kind of funny though, finishing it kind of makes me wish it was an actual mini-series instead of a one-shot. Now I kind of want a mini series of the present Miles ending up in that alternate future.
