She was active in many community groups and a member of the historic Pilgrim Baptist Church, known as the birthplace of modern gospel music. She was married twice and had one daughter, now deceased.Cook's family shared that she was born and raised in Alabama by her grandparents, who were former slaves. They called her an "excellent family historian" who has traced their family tree and shared her family's rich history with younger generations.In addition to good genes, her family credits her upbringing as one of the reasons she has lived such a long, healthy life. Since affordable doctors were hard to come by back then, Cook's family practiced herbal medicine.Another secret to her longevity? Milk.
