So where do these new people come from? At first I thought that they might be new children born to people who died or were incarcerated in the book universe, like Bellatrix's daughter and Neville's younger sister. But then I realized that since these children are around Harry's age, they'd all have been born before we went AU. So these are children that were, at least, born in the book universe as well. So why didn't we see them at Hogwarts?
With Katrina Bundy, she may actually have been there and never named, because there was something about an unnamed Gryffindor girl at HP Lexicon.
With Stephen Capper, could it be Stephen Cornfoot, but maybe with a different last name? Maybe if his parents got divorced or remarried soon after he was born, they would have changed his last name. Or if he is a half-blood, maybe his name was changed to that of his wizarding parent rather than his Muggle parent.
There are two others. Assuming they weren't actually there in the books but unnamed, they could either be children who in canon were casualties of the Death Eater round-up after Voldemort's defeat (like Neville's parents were), or they could be related to some of the wizards who immigrated to England when Voldemort took power (like Pascoal (http://alt-bellatrix.livejournal.com/1566.html?thread=5662#t5662)). Or they could be homeschooled in the books by overprotective parents who didn't want them to be exposed to Dumbledore's ideas or to attending school with Muggleborns.
My theory about the blue names
