O'Cawley is a surname in the English language. According to John O'Hart, a 19th-century Irish genealogist, the surname is an Anglicised form of the Irish Ó Cadhla.[1] The Irish Ó Cadhla originated as a patronym, meaning "descendant of Cadhla". The masculine personal name Cadhla means "beautiful", "comely", "graceful".[2] In the United States of America the surname is extremely uncommon, and did not rank in the 2000 United States Census.[3]
