Aelius was born
Lucius Ceionius Commodus, and became
Lucius Aelius Caesar upon his adoption as Hadrian's heir. He is sometimes referred to as
Lucius Aelius Verus, though this name is not attested outside the
Historia Augusta, where it probably was originally the result of a manuscript error. The young Lucius Ceionius Commodus was of the
gens Ceionia. His father, also named
Lucius Ceionius Commodus (the
Historia Augusta adds the cognomen Verus), was consul in 106 and his paternal grandfather, also of the same name, was consul in 78. His paternal ancestors were from
Etruria, and were of consular rank. His mother is surmised to have been an undocumented Roman woman named
Plautia. The
Historia Augusta states that his maternal grandfather and his maternal ancestors were of consular rank. Before 130, the younger Lucius Commodus married
Avidia, a well-connected Roman noblewoman who was the daughter of the senator
Gaius Avidius Nigrinus. Avidia bore Lucius at least one son and two daughters, who were: • Lucius Ceionius Commodus – The future
Lucius Verus, co-emperor with
Marcus Aurelius from 161 until his own death in 169. Verus would marry
Lucilla, the second daughter of Marcus Aurelius and
Faustina the Younger. •
Ceionia Fabia – at the time of Marcus Aurelius's adoption, she was betrothed, as part of the adoption conditions, to him. Shortly after
Antoninus Pius' ascension, Pius came to Aurelius and asked him to end his engagement to Fabia, instead marrying Antoninus Pius’ daughter
Faustina the Younger; Faustina had originally been planned by Hadrian to wed Lucius Verus. •
