Avidia Plautia
Avidia Plautia (flourished 2nd century) was a well-connected noble Roman woman.
She is among the lesser known members of the ruling Nerva–Antonine dynasty of the Roman Empire.
Plautia was the daughter of the well-connected Roman Senator Gaius Avidius Nigrinus and the surmised but undocumented Roman noble woman Ignota Plautia.
The younger Plautia was born and raised in Faventia (modern Faenza, Italy).
Her family was distinguished, wealthy and well-connected.
Her family were friends of the Greek historian Plutarch, Roman Senator Pliny the Younger, Roman Emperor Trajan and his family.
Her family had strong links to Greece, as her paternal grandfather Gaius Avidius Nigrinus had served at an unknown date during the reign of Roman Emperor Domitian (81-96) as Proconsul of Achaea, a position in which her great uncle Titus Avidius Quietus had also served.
Her family may have been related to the consul Gaius Petronius Pontius Nigrinus, who had served his consulship at the time that the Roman Emperor Tiberius had died in 37.
Plautia's father was executed in 118 on orders from the Roman Senate, because he was one of four senators involved in a failed plot to overthrow the Roman Emperor Hadrian.
Sometime after her father’s execution, her mother Ignota Plautia may have married another Roman senator.
Before 130 Plautia married the powerful Roman Senator Lucius Aelius Caesar.
Aelius was adopted by Roman Emperor Hadrian in 136 as his first heir.
Plautia bore Aelius
two sons and two daughters who were:
In early 138, Aelius died, and Hadrian had adopted Antoninus Pius as his second son and heir.
On the condition that Antoninus Pius was adopted by Hadrian, Antoninus had to adopt Lucius Verus and Marcus Aurelius as his adopted sons.
If Aelius had lived long enough to succeed Hadrian and rule as emperor, Plautia could have been an Empress of Rome.
It is unknown whether Plautia remarried after the death of Aelius.
Three existing portrait busts have been identified as Avidia Plautia because of physical similarities to the portrait busts of her son Lucius Verus.
These busts have been dated to 136-138, when Aelius was the first adopted heir of Hadrian.
When her son reigned as co-Roman Emperor with Marcus Aurelius, Lucius Verus dedicated two honorific inscriptions to his mother.
These inscriptions have been found in Rome.
The inscriptions honor her as the daughter of Gaius Avidius Nigrinus and the mother of Roman Emperor Lucius Verus.
It is unknown whether Plautia lived long enough to see her son co-rule as emperor.

Ceionia Fabia
Ceionia Fabia (flourished 2nd century) was a noble Roman woman and a member of the ruling Nerva–Antonine dynasty of the Roman Empire.
Fabia was the first-born daughter to Lucius Aelius and Avidia Plautia.
In 136, her father was adopted by Hadrian as heir to the throne.
Fabia had three siblings: a sister Ceionia Plautia and two brothers: the Roman Emperor Lucius Verus who co-ruled with Marcus Aurelius from 161-169 and Gaius Avidius Ceionius Commodus.
Her cognomen "Fabia" reveals that her father was related to the gens Fabia.
However, whom she was named after from the gens Fabia is unknown.
Fabia was born and raised in Rome.
Her maternal grandparents were the Roman Senator Gaius Avidius Nigrinus and the surmised but undocumented noblewoman Ignota Plautia.
Although her adoptive paternal grandparents were the Roman Emperor Hadrian and Roman Empress Vibia Sabina, her biological paternal grandparents were the consul Lucius Ceionius Commodus and noblewoman Aelia or Fundania Plautia.
Sometime in 136 after Hadrian announced that her father was to be the Emperor’s official heir, on the wishes of Hadrian, the emperor betrothed Fabia to Hadrian’s great-nephew Marcus Aurelius.
Although Fabia and Aurelius became engaged, the engagement did not survive Hadrian; immediately after the emperor's death, Antoninus Pius, Hadrian's second adopted son and the new emperor, approached Marcus and requested that his marriage arrangements be amended: Marcus' betrothal to Ceionia Fabia would be annulled, and he would be betrothed to Faustina, Antoninus' daughter, instead.
Faustina's betrothal to Ceionia's brother Lucius Commodus would also have to be annulled.
Marcus consented to Antoninus' proposal.
Fabia later married the nobleman Plautius Quintillus who came from a family of consular rank.
During the reign of Antoninus Pius (138-161), Quintillus served as an ordinary consul in 159.
Fabia bore Quintillus a son called Marcus Peducaeus Plautius Quintillus who later married Annia Aurelia Fadilla, one of the daughters of Marcus Aurelius and Faustina the Younger.
Throughout the Roman Empire, various honorific inscriptions have survived being dedicated to Fabia and her family.
These inscriptions honor Fabia as the mother of Marcus Peducaeus Plautius Quintillus; the sister of Roman Emperor Lucius Verus and the sister-in-law of Empress Lucilla (the second daughter of Marcus Aurelius and Faustina the Younger, who was one of the sisters of Fadilla).
According to an inscription found at Ephesus, Fabia was present when Lucius Verus married Lucilla.
It appears by 175 her husband had died.
When Faustina the Younger had died in 175, Fabia was said to have attempted to interest Marcus Aurelius in a second marriage.
However, Marcus Aurelius preferred to take a mistress, who was a daughter of one of Faustina’s procurators.
