King was born Michael King Jr. on January 15, 1929, in Atlanta, Georgia, the second of three children to the Reverend Michael King Sr. and Alberta King (née Williams). King's mother named him Michael, which was entered onto the birth certificate by the attending physician. Although, King Sr. would later state that "Michael" was a mistake by the physician. King's older sister is Christine King Farris and his younger brother was A. D. King. King's maternal grandfather Adam Daniel Williams, who was a minister in rural Georgia, moved to Atlanta in 1893, and became pastor of the Ebenezer Baptist Church in the following year. Williams was of African-Irish descent. Williams married Jennie Celeste Parks, and they gave birth to King's mother, Alberta. King's father was born to sharecroppers, James Albert and Delia King of Stockbridge, Georgia. Michael King Sr. and Alberta began dating in 1918, and married on November 25, 1926. Until Jennie's death in 1941, they lived together on the second floor of her parent's two story Victorian house, where they brought up their children.
