The Blacks were a prestigious family in Diamond City, residing in the upper-stands. Despite Evelyn and her husband's best efforts, Mags and William grew up to be rowdy and rebellious, constantly causing all sorts of mischief with their friend Lizzie Wyath. After an incident that resulted in the death of a young woman, the three were sentenced to exile from Diamond City. Having grown tired of defending their children's actions and sullying the family name, the Blacks refused to defend their children and assist them financially, even refusing them their inheritance. Mags' reply suggests that she and her brother might have tried to take the inheritance by force, which would explain Evelyn's absence from Diamond City in 2287. According to Mags, their mother physically abused them.
