Born on May 2nd in Oxfordshire England, Nicole was the oldest of two children to her parents Michael and Catherine Arnett. As a half blood, her parents both magical, she knew of the magical world long before she had received her letter to Hogwarts. Their middle class family lived in a muggle neighbourhood and she grew up attending a muggle primary school before entering her education at Hogwarts, much to her father's chagrin. She has a younger sister Lily Arnett of whom after an accident when Lily was three years old would result in her Aunt and Uncle having to support Lily, but with their muggle backgrounds, Nicole felt responsible for Lily's magical upbringing.
