Omg they're my age

Me too, I'm head girl and Hugo is head boy ;) I saw Harry at the platform and he said I have his mother's eyes.

Actually is only Lily's. Hugo is one year younger than her.

@Wikibianca Black-Grindelwald That's a possibility. Hugo is still in the same school year as Lily though. He just wasn’t shown in Cursed Child.

The quote from his page says:

In the last chapter of Harry Potter and the Deathly Hallows, he and his cousin Lily discuss what house they will be sorted in and since Hugo shows no sign of envying Lily for being allowed to go first, it is likely that they are in the same year at Hogwarts. However, it is also possible that he is at least one year younger than Lily since he is not sorted in The Cursed Child while Lily is.

So maybe he was born after 1 September and that's why he is a year after Lily. It happened to Hermione

Well, I don't believe the Cursed Child is canon, so Hugo is in Lily's year.

The Cursed Child is canon according to JK Rowling, it's just that most of the fans decide to not accept it as canon

Who do you think is younger than Lily & Hugo? Is it Fred & Roxanne? Or Molly & Lucy?

When Lily is eleven, I'd say Roxanne is twelve and Fred is nine, and than Moly and Lucy are like eight and seven/six more or less
