John Singleton Copley, Jr. was born in Beacon Hill on 21 May 1772 to the American artist John Singleton Copley and his wife, née Suzannah Farnum Clarke. In 1774 John Singleton Copley left his native Boston to continue his artistic studies in Europe; in 1775 his family joined him in London. John, Jr. attended Trinity College, Cambridge, and was admitted to the bar in 1804. John Singleton Copley, Jr., later became Lord Lyndhurst, Lord Chancellor to Queen Victoria, the first American to hold this title. Lord Lyndhurst occupied his father's home on George Street, Hanover Square until his death at age 92 in 1863. John Singleton Copley painted a portrait of his family, including Lord Lyndhurst as an infant, shortly after their arrival in England; this painting is now in the NGA (1961.7.1).
