Dalmatius the Censor
Flavius Dalmatius was the son of Constantius I and his wife Theodora, and the half-brother of the Emperor Constantine I . His two sons, by an unknown wife, Flavius Dalmatius and Hannibalianus held high offices in their uncle's administration. Although his early years seem to have been spent in Gaul at the city of Tolosa, he may have been recalled as early as the mid 320s. In any case, he was named a consul and censor in 333. In Antioch, where he seems to have been in charge of the Eastern frontier, he investigated a murder charge against Bishop Athanasius of Alexandria; in 333/334 he put down the revolt of the usurper Calocaerus in Cyprus. In 335, with some soldiers under his command, he was able to save Athanasius from certain death at the hands of his foes at the Council of Tyre. He was among those who perished in the imperial purges of 337 which followed the death of the Emperor Constantine in May of that year.
Eutropia and Her Husband Virius Nepotian
Eutropia was the daughter of Theodora and her husband Constantius I , and the half-brother of the Emperor Constantine I. She married Virius Nepotian, consul in 336, and bore him a son named Nepotian . When Magnentius was proclaimed emperor in 350/1, her son was acclaimed emperor for a period of 28 days in early June 350. Subsequent to her son Nepotian's death at the end of that month, she seems to have been put to death by Magnentius .
Hannibalianus
Hannibalianus was the son of Constantius I and his wife Theodora and the half-brother of the Emperor Constantine I . Not much else is known about this shadowy individual except that he must have died before the imperial purges that occurred in 337 because he is not listed among its victims. The other half-brothers of Constantine I are known to have perished at this time.
Julius Constantius and His Wives
Julius Constantius was the son of Theodora and her husband Constantius I , and the half-brother of the Emperor Constantine I Like his brother Flavius Dalmatius, he seems to have spent his youth under house arrest in Tolosa, and later in Corinth. He must have been recalled from exile ca. 325 or326 because his first wife Galla, the sister of Vulcacius Rufus and Neratius Cerealis, bore him his son Gallus at Massa Veternensis in Tuscany. She also bore him an son who died in the imperial purges in 337 and a daughter who became the first wife of the Emperor Constantius II in 335 or 336. The names of these two children have been lost from the historical record. He was consul in 335 with Ceionius Rufius Albinus and made a patricius by his half-brother. Galla must have died because he subsequently married Basilina, the daughter of Caeionius Iulianus Camenius. The only offspring of this union was the Emperor Julian. She passed away within several months of his birth. Constantius did not outlive brother Constantine by much because he perished in the imperial purges of 337.
