I dont known, I think he was her son, at least in comics, and not now in Tv show or movies.
Well, other things happend in comics that dont happend in movies or Tv show, at least in the old comics, for example, in the comics before Raimi (Spiderman), Peter and Mary Jane get divorced, because she cant stand his life as Spiderman, and their lose her child.
Another example is the old X Men comics, where Scott Summers and Jean Grey divorce each other, not matter their alternate children, Summers is a cheater, first with Emma Frost, and then after Jean die, he marry her clone, the Goblin Queen, but after Jean come back from the dead, he left her clone, with his child to be with Jean, her fall for the dark side for that, and become a villain, and never the less, Jean and Scott dont last long after that, so Scott isnt the best of characters.
