Domitilla the Younger

Flavia Domitilla the Younger or Flavia Domitilla Minor (c. 45 – c. 66) was the only daughter of the Roman Emperor Vespasian.

Biography
She was the child of Vespasian and his wife Domitilla the Elder. She was born after her brother Titus and before her brother Domitian. At the age of fifteen, she was married to Quintus Petillius Cerialis, with whom she had a daughter, the later Christian saint Flavia Domitilla.

Domitilla died before Vespasian became emperor in 69. She was later deified by her younger brother Domitian, who also bestowed the honorific title of Augusta upon her.
