I suppose four does seem as a lot when you're a parent. And a sibling, even. It can be a pain to have a bunch of younger siblings, especially when they decide that you should help them do
all their essays and stuff. I doubt you would have too much trouble with four children, though. You're a great captain and some of our House's players can be idiots sometimes. And I bet that you would make a wonderful father.
Maybe they could even learn about potions from their aunt? Your sister does like them, right? As for the aunts from my side of the family... They better not be too influenced by Saoirse, I guess. But Sib could give them books and stuff. Though I admit, I would much rather give them broomsticks rather than books.
As for names... Irish, maybe? If you don't mind, of course. Or your father. But I know for sure that I don't want ordinary names like Jane or John or something.
