In his later years, he married a relative, Caecilia Pilea/Pilia (c. 75 – 46 BC), daughter of Pileus/Pilius and a maternal granddaughter of the Triumvir, Crassus. Atticus and Pilea/Pilia were married in 58/56 BC, when Atticus was already 53/54 years old, and she died after 12 years of happy marriage. She bore him a son of the same name, Titus Pomponius Atticus (of whom little is known), as well as a daughter, Caecilia Pomponia Attica, who became the first wife of Marcus Vipsanius Agrippa.
