Evan Rosier I

Evan Rosier was a pure-blood wizard and a student in Slytherin House of Hogwarts School of Witchcraft and Wizardry. He was a member of a gang during his school years, alongside Severus Snape and several other individuals who eventually became Death Eaters. Shortly after graduating Hogwarts, he entered into an arranged marriage with his wife, as well as entering into the service of Lord Voldemort in the First Wizarding War. They had two children.

The Rosiers were very traditional both in the magical and social sense, and thus did not allow their daughter Eva to express her gender identity. He was forced to acknowledge it when the staff at Hogwarts (specifically Minerva McGonagall) helped her magically transition to female, When this happened, he begrudgingly used the correct name and pronouns to refer to her, although he did not correct his wife's misgendering of her.

By 1993, it seemed that he had fallen out of favor with Voldemort, as he dismissed him and his family from dinner for impudence.
