"Acilius Glabrio's name presents a problem, due to its polyonymous nature. In short, he has multiple names—"Manius Acilius Glabrio" and "Gnaeus Cornelius Severus"—which is baffling to anyone more familiar with the tria nomina of the Late Republic and Early Empire. This polyonomy can be explained one of three ways:
1 he was born Cn. Cornelius Severus and adopted by M'. Acilius Glabrio, based on the common custom of putting the name of his adoptive father before his natural father's; or
2 he was born M'. Acilius Glabrio and adopted by a Gnaeus Cornelius Severus (in this case, most likely the consul of 112, based on the less common custom of putting the name of his natural father before his adopted father's); or
3 his mother was the daughter of Cn. Cornelius Severus, consul 112, and he attached her name to the end of his father's out of respect for her family, which was an increasingly common custom in the second century."
He is married to Annia Vibia Faustina.
