Who dated Annia Cornificia Faustina Minor?

Annia Cornificia Faustina Minor (Minor Latin for the younger, 160–212 AD) was a daughter of the Roman emperor Marcus Aurelius and his wife, Faustina the Younger. She was sister to Lucilla and Commodus. Her maternal grandparents were Antoninus Pius and Faustina the Elder, and her paternal grandparents were Domitia Lucilla and praetor Marcus Annius Verus. She was named in honor of her late paternal aunt Annia Cornificia Faustina.

Publius Helvius Pertinax ( PER-tin-ax; 1 August 126 – 28 March 193) was Roman emperor for the first three months of 193, succeeding Commodus and becoming the first ruler of the turbulent Year of the Five Emperors.

The son of a freedman, Pertinax rose from modest origins through a military career. He distinguished himself in the Roman–Parthian War of 161–166 and went on to hold a succession of governorships and senior commands. He also sat in the Roman Senate, where he was a contemporary of the historian Cassius Dio.

After the assassination of Commodus, Pertinax was chosen emperor. He aimed at restoring army discipline and imperial financial stability, but his reforms angered the Praetorian Guard, who killed him after just 87 days. He was later deified by Septimius Severus, who promoted his memory as part of his own rise to power. Ancient and modern assessments generally view Pertinax as a capable and conscientious ruler undone by circumstances.
