Octavius Winslow descended from Edward Winslow, a Pilgrim leader who braved the Atlantic to come to the New World on the Mayflower in 1620. Octavius' father, Thomas, an army captain stationed in London, died when he was seven years old. Shortly after that, Octavius' God-fearing mother took her family of ten children to New York. All of the children became Christians, and three sons became evangelical ministers. Octavius later wrote a book about his family's experiences from his mother's perspective, titled Life in Jesus. Winslow was ordained as a pastor in 1833 in New York. He later moved to England where he became one of the most valued nonconformist ministers of the nineteenth century, largely due to the earnestness of his preaching and the excellence of his prolific writings. He held pastorates in Leamington Spa, Bath, and Brighton. He was also a popular speaker for special occasions, such as the opening of C. H. Spurgeon's Metropolitan Tabernacle in 1861. After a short illness, he died on March 5, 1878, and was buried in Abbey Cemetery, Bath. Winslow wrote more than forty books, in which he promoted an experimental knowledge of the precious truths of God.
