[3] Aemilia and her siblings all took the family name of their mother, which historian Hagith Sivan noted was uncommon for the time.
Her nephew, Ausonius, reported that she continued to act in a more masculine manner into her childhood and dress in a less feminine manner into adulthood, which may have led to her remaining unmarried; however, it is notable that during this time period Christian women were encouraged to hide their feminine appearances by the clergy.
It is unknown if Aemilia Hilaria was a Christian; Ausonius's phrasing seems to imply that she was, but may simply be poetic writing.
Ausonius wrote a series of biographical poems about his family members, including Ameilia, called Parentalia.
[7] Aemilia is a featured figure on Judy Chicago's installation piece The Dinner Party, being represented as one of the 999 names on the Heritage Floor.
