Early life and education
Minna Mabel Collins on September 9, 1851 at St Peters Port, Guernsey. Her parents were Edward James Mortimer Collins, a self-taught poet and journalist, and Susanna Hubbard, a merchant's daughter. When they married, Mortimer was nineteen years younger than his wife, who already had six children. The family moved frequently, as Mortimer repeatedly overspent and landed in debtors' prisons. "By the time she was twelve years old Minna had begun to write romances and verse herself. She had never attended school – what education she had was from her father. Poetry and philosophy formed the main content of her lessons." 
Young Minna began a new life when she married Keningale Robert Cook on August 3, 1971 at St. Peters Church in Knowl Hill. He was six years older than she, and was well educated at Rugby and Trinity College in Dublin. He earned several degrees culminating in a Doctorate in Laws in 1875. During the years at Trinity College he was employed by the Post Office dealing with money orders, but by 1875 he had become a stockbroker in London. He published a book of poetry and numerous articles for the magazine Woman. This same magazine began to publish Minna's writings as well. "Almost every issue contained Minna’s or Robert’s writings. They covered a range of subjects but were primarily concerned with education, the role of women and the arts."
