Fabia Numantina

Fabia Numantina is generally believed to be the daughter of Paullus Fabius Maximus and Marcia, a maternal first cousin of Augustus (daughter of his aunt Atia and his step-brother Philippus). However, it is possible that she was the daughter of Paullus' brother, Africanus Fabius Maximus.

Marriages

Fabia Numantina was married twice:

Firstly to Sextus Appuleius (III), a half-great-nephew of Augustus, by whom she had a son, Sextus Appuleius (IV), who died young and who Fabia set up a tombstone to as 'last of the Appuleii'.

Secondly to Marcus Plautius Silvanus, the praetor in 24, son of Marcus Plautius Silvanus, consul in 2 BC, and his wife, Lartia. However, they seem to have been divorced prior to 24, as Silvanus was by then married to a woman named Apronia, who he apparently murdered by throwing her out of a window.

Shortly after the murder of Apronia, Fabia was "charged with having caused her husband's insanity by magical incantations and potions", but was acquitted.

Other Children

It is uncertain if Fabia had any children apart from Sextus Appuleius (IV). One possibility is a young man named Fabius Numantinus, who was admitted to a sacerdotal college in the Neronian era.
