Hugo Weasley (born sometime after August 2006) was a half-blood wizard and the child of Ronald and Hermione Weasley (née Granger). He has an older sister named Rose who attended Hogwarts School of Witchcraft and Wizardry from the 2017-2018 school year onwards.
Hugo Weasley was born after August 2006 (as he is specified to be younger than Rose and not going to Hogwarts in the same year as her) to a pure-blood father and a Muggle-born mother, making him half-blood. He is about two years younger than his sister Rose, and around the same age as his cousin Lily Potter, daughter of Harry and Ginny Potter, and the two seem to be quite close. In 2017, he accompanied his parents to see off his sister and his Potter cousins to Hogwarts School of Witchcraft and Wizardry. Hugo and Lily shared an eagerness to go to Hogwarts, despite both of them being too young. At King's Cross Station, the two had "an animated discussion about which House they would be sorted into when they finally went to Hogwarts" 
Although it is not specified when, it is likely he will attend Hogwarts School of Witchcraft and Wizardry when he turns eleven. While some fans have speculated that he is around the same age as Lily, this is not confirmed.
Hugo, like his elder sister Rose, takes after their paternal family in looks. He has his father's red hair and blue eyes.
It is also possible that Ron and Hermione wanted their children to have the same initials as their parents, R and H. Interestingly, both children also have names consisting of four letters.
