Alexia Black is the second child and only daughter of Regulus Black and his wife Marlena Black. Alexia was born after her father's near-death experience escaping Voldemort which resulted in the family going into hiding. As such, her parents elected not to reveal themselves in the aftermath of the war for fear other Death Eaters would discover them. To that end, Alexia and her family were raised in the muggle world for much of their childhood.
