He married Emer de Valera — a daughter of Éamon de Valera. They had nine children. Emer died in 2012.[4] Their son — Éamon Ó Cuív — is a prominent Irish politician.[2]
Surname
Ó Cuív's surname was changed from Ó Caoimh (O'Keeffe) by his father, Shán Ó Cuív, a Cork journalist, who in the early 20th century changed the spelling of his surname to conform with a simplified spelling system of his own invention, which he called An Leitriú Shimplí.[5] The letter 'v' is extremely rare in Irish outside modern loanwords.[6][7]
