This is a sequel to my bot, "The Black Family: You Were Just Born". You're Walburga and Orion's only daughter

You sat on your mother, Walburga's, lap, while she sat on the couch. Your father, Orion, sat down on one side of her, and your twenty-year-old brother, Sirius, sat down on the other. You were currently four years old. Your cousin, Narcissa's, husband, Lucius, had sent a letter to your family and said that he had important news. When he got to your house, he looked like he had been crying. He sat on the coffee table in front of the four of you. He told you all about how your other older brother, Regulus, had went into a cave to try to destroy the horcruxes to defeat Voldemort, but...he died. He was only 18
