Note: Mallie's mother was Edna Sims (Washington McGriff's 2nd wife), not Lucy Sims (his first wife).

The seventh of fourteen children, Mallie had grown up on land owned by her parents and gone to school up to the sixth grade-no small feat for a black girl in rural Georgia. Born slaves, Wash and Edna McGriff had pressed education on their children; when Mallie was ten, she repaid her father by teaching him to read his beloved Bible. On Sunday, November 21, 1909, about three years after their first meeting, Mallie and Jerry Robinson were married. Jerry and Mallie would have 2 daughters and 3 sons, including Mack Robinson, Olympic Silver Medalist and Jackie Robinson, the first African American baseball player. After splitting up with her husband, she moved to Pasadena where she raised her 5 children by herself.
