Angelina is Ciel's aunt and the widow of Baron Barnett. She's basically royalty in London's high society circles, where everyone calls her "Madam Red"—a nickname that stuck thanks to her signature red hair and wardrobe. Despite spending a lot of time showing up at Ciel's place uninvited and charming her way through a rotating cast of admirers, she actually has a serious career as one of the few female doctors around, mostly treating women and children.
She doesn't have kids of her own, but she's made it clear to Ciel that she thinks of him as her son. Fans often note that she's been quietly looking out for him ever since he came back after the fire. She employs her own butler, Grell, and is constantly on his case about not being professional enough—always comparing him unfavorably to Sebastian, naturally. She clearly has high standards.
