Somerset Club

In 1851 the group purchased the home of Benjamin W. Crowninshield, located at the corner of Beacon and Somerset Streets.

During the Civil War, members of the Somerset Club split along political lines.

Somerset defectors formed the Union Club of Boston in 1863, which demanded "unqualified loyalty to the constitution and the Union of our United States, and unwavering support of the Federal Government in effort for the suppression of the rebellion."

The land on which the house stood was originally part of an 18-acre (73,000 m2) parcel owned by John Singleton Copley, who called it "his farm on Beacon Street."

Eventually the Club bought 43 Beacon Street and joined the two houses into one large clubhouse.
