Do Ты know which house did the kids sorted to?

I bet they are all in Gryffindor, but Rose could be a Ravenclaw, because she's so smart and everything... But that's just me...maybe JK сказал(-а) something about it and I haven't heard it yet, who knows?...

they were all in Griffendor but Rose was in Ravenclaw and Albus and Dominic were in Slythrin

Well, no one actually knows (apart from JKR obviously) but Ты can guess.
I think James is in Griffindor because of how he was teasing Albus that he might be in Slytherin.
Albus will be in either Griffindor или Slytherin depending on how he uses his father's Совет in the epilogue.
I think Scorpio Malfoy will be in Slytherin like the rest of the family.
Most of the other Weasley grandkids will be in Griffindor, with the occasional Hufflepuff and Ravenclaw.
