5. Daughter of Sex. Pompeins Magnus, the son of the triumvir and of Scribonia. At the peace of Misenum in B. C. 39 she was betrothed to M. Claudius Marcellus, the son of Octavia, the sister of Octavian, but was never married to him. She accoimpanied her father in his flight to Asia, B. C. 36. (Appian, App. BC 5.73; D. C. 48.38, 49.11.) She is not mentioned after this time, but it has been conjectured by commentators, with much probability, that she may have married Scribonius Libo, and had by him a son, Scribonius Libo Drusus; since Tacitus (Tac. Ann. 2.27) calls Pompeius, the triumvir, the proavus of Libo Drusus ; Scribonia, the wife of Augustus, his amita; and the two young Caesars his consobrini. The descent of Libo Drusus would then be, 1. Cn. Pompeius, the triumvir, proavus. 2. Sex. Pomlpeius, avus. 3. Pompeia, mater. 4. Libo Drusus.
