Sanguini

Sanguini is a vampire who attended a Slug Club Christmas party during Harry Potter's sixth year at Hogwarts School of Witchcraft and Wizardry. He was the guest of Eldred Worple. The tall, emaciated man had dark shadows under his eyes and looked bored with the party until a nearby group of girls attracted his attention. Worple tried to distract him from the girls by shoving a pasty into his mouth.

Name etymology
The name Sanguini most likely originates from the French sang, meaning "blood" and hence vampirism. It could also come from exsanguination, which means "to bleed out".

Ultimately probably derives from the latin 'sanguineus', meaning of blood, bloody, blood-coloured or bloodthirsty. Also from the English adjective 'sanguine' which relates to blood - describes a blood colour or having an active, warm and lively circulation or temper.
