Galla is listed as one of four children of the marriage by Jordanes. Her paternal uncle Valens was Emperor of the Eastern Roman Byzantine Empire from 364 to his death in the Battle of Adrianople (9 August 378). Her father was emperor of the Western Roman Empire from 364 to his death on 17 November 375 and was previously married to Marina Severa. The only known child of that marriage was Gratian, Western Roman Emperor from 375 to his assassination on 25 August 383. Her mother was previously married to Magnentius, a Roman usurper from 350 to 353.[1][2] However both Zosimus and the fragmentary chronicle of John of Antioch report that Justina was too young at the time of her first marriage to have children.[3] Galla thus had no known maternal half-siblings.

Galla had three full-siblings. Her only brother was Valentinian II, first co-emperor with Gratian from 375 and then the only legitimate Western Roman Emperor from 383 to his death by hanging on 15 May 392. His death was officially reported as a suicide but Arbogast, his magister militum was suspected to have had a hand in it, an accusation found in the writings of Socrates of Constantinople, Orosius, and Zosimus. Sozomen was less certain and mentioned both versions of how Valentinian II died.[4]

Her two sisters were Grata and Justa.[5] According to Socrates, both remained unmarried. They were probably still alive in 392 but not mentioned afterwards.[5]

When Galla married Theodosius, she became both a Roman Empress and a stepmother to Theodosius’ two sons from his first marriage, Arcadius and Honorius.

According to Zosimus, she died in childbirth in 394, the exact date unknown.[6]
