Eutropia (sister of Constantine I)

Eutropia (died 350) was the daughter of Roman emperor Constantius Chlorus and Flavia Maximiana Theodora, and therefore half-sister of Constantine the Great.[1] She was mother of the short-lived imperial pretender Nepotianus, and was probably killed alongside him by the rival usurper Magnentius in 350.[2]

She was married to Virius Nepotianus, who had been consul in 336, and was a favourite of Constantine the Great.[3]

Her murder was mentioned by Athanasius of Alexandria in his Apologia ad Constantium, written to Emperor Constantius II, among others who were killed by Magnentius:

...butchering those who so kindly entertained me at Rome; for instance, your departed Aunt Eutropia, whose disposition answered to her name.[4]

The source also indicates that she was an acquaintance of Athanasius who met her when he previously stayed at Rome.
