Eutropia (princess)
Eutropia was the daughter of Emperor Constantius Chlorus and of Flavia Maximiana Theodora, and therefore half-sister of Emperor Constantine the Great.Biography
She married Virius Nepotianus and bore him a son, Nepotianus, who later became a short-lived Roman usurper, when Magnentius was proclaimed emperor in 350; after a period of twenty-eight days in early June 350, Nepotianus was killed, and probably this led to the execution of Eutropia by order of Magnentius' magister officiorum Marcellinus.
