Members of this gens held various positions of authority from the time of the Second Punic War, and Titus Annius Luscus attained the consulship in 153 BC.
[2] The Annii claimed a descent from the goddess Anna Perenna, the sister of Dido, portrayed on the coins of Gaius Annius Luscus.
[4][5] It seems the gens acquired the citizenship soon after, since a Roman senator named Annius is recorded a generation later.
Other names occur infrequently, although in imperial times several of the Annii used Appius, an otherwise uncommon praenomen chiefly associated with the Claudii.
[6][7] A variety of surnames were borne by individual Annii, including Asellus, a diminutive of asinus, a donkey; Bassus, stout; Cimber, one of the Cimbri; Faustus, fortunate; Gallus, a Gaul or cockerel; and Pollio, a polisher.
