Patsy is a given name often used as a diminutive of the feminine given name Patricia or sometimes the masculine name Patrick, or occasionally other names containing the syllable "Pat" or "Pet" (such as Cleopatra, Patience, or Patrice). Among Italian-Americans, it is often used as a pet name for Pasquale.
In older usage, Patsy was also a nickname for Martha or Matilda, following a common nicknaming pattern of changing an M to a P (such as in Margaret → Meg/Meggy → Peg/Peggy; and Molly → Polly) and adding a feminine suffix. President George Washington called his wife, Martha, "Patsy" in private correspondence, while President Thomas Jefferson's eldest daughter Martha was known by the nickname "Patsy," while his daughter Mary was called "Polly."
While usually a feminine diminutive name, from the 18th century, Patsy also came to be used as a nickname for men and boys called Patrick.
The popularity of the name has waned with the rise of its, chiefly North American, meaning as "dupe" or "scapegoat". This usage may come from the vaudevillian Billy B. Van, whose 1890s character, Patsy Bolivar, was more often than not an innocent victim of unscrupulous or nefarious characters. At least two murderers have been recorded using this word, to refer to themselves, after their killings: Lee Harvey Oswald, after murdering USA president John Kennedy, and Byron Smith, after murdering Haile Kifer, and her cousin, Nicholas Brady.
