Allycroker, foaled in 1758, was one of Thomas Jefferson's earliest recorded riding horses. Inherited from John Wayles, Allycroker became one of Jefferson's primary breeding mares. Her foals included Cucullin, Alfred, Caractacus, and Orra Moor. "Ally Croker" was a popular eighteenth-century Irish folk song. Her date of death is unknown, but there are no references to her in Jefferson's records after 1778.
