 He was a son of Reverend Martin Luther King Sr. (1899–1984), and Alberta Williams King (1904–1974), the youngest of their three children (the other two being Willie Christine, born September 11, 1927, and Martin Luther King Jr., born January 15, 1929).In contrast to his peacemaking brother, Martin, A. D.—according to his father—was "a little rough at times" and "let his toughness build a reputation throughout our neighborhood".Less interested in academics than his siblings, King started a family of his own while still a teenager and attended college later in his life.
