Theophilus Herrick, Jr., was born on May 17, 1830, in Gloucester, Massachusetts, to Theophilus Herrick and Dorothy Bray. His father was a farmer and trader who owned $1,500 of real estate in 1850. Herrick grew up and attended school in Gloucester. By 1855, he was working as a brewer. Five years later, he was working as a teacher and living in the household of shoe binder Ruth A. Haskell and her three adolescent children. Herrick may have served in the Union army during the Civil War. He worked as a hotel keeper after the war, and his health deteriorated by the early 1880s. He drowned on July 27, 1882, and newspapers reported it “a case of suicide while mentally deranged.”
