Although none of them ever obtained the consulship, the family was of "senatorial rank",[i] and was well known from the latter half of the second century BC.
In Imperial times, a number of them became distinguished in military and provincial service.
[1] The Granii may have originated at Puteoli, where a Roman colony was established in 194 BC, although it is not known whether the ancestors of the gens were among the original colonists, or natives of the town who acquired Roman citizenship.
[1][2][3][4] The Granii of the Republic used the praenomina Quintus, Gnaeus, Gaius, Publius, and Aulus, all of which were common names throughout Roman history.
In imperial times, the surnames Licinianus, Marcellus, Marcianus, Serenus, and Silvanus are found.
