From the Latin female name, a feminine form of Claudius. The name is mentioned in one of St Paul's letters to Timothy (2, 4:21 ‘Eubulus greeteth thee, and Pudens, and Linus, and Claudia, and all the brethren’), as a result of which it was taken up in the 16th century and has since maintained a steady popularity.
Irish: 1. Anglicized form of Gaelic Ó Conraoi ‘descendant of Cú Raoi’, a name meaning ‘hound of the plain’, which was stressed on the final syllable. 2. Anglicized form of Gaelic Ó Conaire ‘descendant of Conaire’, a byname meaning ‘keeper of the hound’ (an agent derivative of cú ‘hound’).
