In 1854 he married a cousin, Catherine Stevens of Andover, Massachusetts. They had no children. On September 2, 1895, Stevens and his wife were severely injured when they were ejected from their carriage. Stevens fractured several of his ribs and Catherine Stevens broke two bones in her right leg and suffered injuries to her hip and chest.
Political career
Early involvement
Stevens served on the Boston common council in 1856 and 1857 and was president of the body in 1856. Stevens was a delegate to the 1860 Democratic National Conventions in Charleston and Baltimore, where he supported the candidacy of Stephen A. Douglas. After the first convention, sixteen members of the Massachusetts delegation, including Caleb Cushing, Benjamin Butler, James Scollay Whitney, and George B. Loring, broke with the party and participated in the “Breckinridge convention". At the Baltimore convention, Stevens served as the spokesman for the Massachusetts delegation, which supported the eventual nominee - Stephen A. Douglas.
District attorney
In 1874, Stevens was elected District Attorney of Suffolk County. In 1876 he tried Thomas W. Piper, also known as The Boston Belfry Murderer, for the murder of Mabel H. Young. The trial ended in a hung jury, with nine voting to convict and three voting to acquit. Piper was later tried and convicted by Massachusetts Attorney General Charles R. Train. On March 1, 1882, Stevens, under instruction from Massachusetts attorney generalGeorge Marston, wrote to James R. Osgood & Co. informing them that their 1881 printing of Walt Whitman's Leaves of Grass violated the law against obscene literature and requesting that they withdraw it from circulation. On March 23, Osgood & Co. wrote to Whitman that if two poems - "A Woman Waits for Me" and "Ode to a Common Prostitute", were removed, the government would allow the book to be published. Whitman rejected this request and Osgood & Co., not wanting to get involved with a lawsuit, ceased publishing the book and turned over the plates to Whitman. Rees, Welsh, & Co. of Philadelphia agreed to publish the Leaves of Grass and the controversy surrounding the book made it a financial success. By January of 1905, Stevens was unable to do much work due to rheumatism. He spent the entire summer at his farm in North Andover. On July 31, 1905, Stevens resigned effective the confirmation of his successor. On August 2, Stevens' first assistant Michael J. Sughrue was appointed by Governor William Lewis Douglas and immediately confirmed by the Massachusetts Governor's Council. Stevens died on August 23, 1905 at his home in North Andover.
