The poet Vergil linked the family of the Memmii with the Trojan hero Mnestheus. This late tradition suggests that by the end of the Republic, the gens had become a conspicuous part of the Roman nobility. The nomenMemmius is classified by Chase with those gentilicia that either originated at Rome, or cannot be shown to have come from anywhere else. From its morphology, the name could be derived from a cognomen, Memmus, the significance of which is unknown. The use of Quirinus, a Sabine deity, on the denarii of Gaius Memmius in 56 BC, perhaps alludes to a Sabine origin of the gens.
The Memmii of the Republic do not appear to have been divided into distinct families, but they used a number of personal surnames, including Quirinus, thought to have been the name of a Sabine god, who came to be equated with both Janus and Romulus; Gallus, referring to a cockerel, or perhaps to a Gaul; and Geminus, traditionally given to a twin. Other cognomina are found in imperial times, including Maximus, given to an eldest brother, or someone particularly notable; Regulus, a diminutive of rex, a king, used by a number of old Roman families; Pollio, a polisher, particularly of armour; Afer, referring to the province of Africa; and Senecio, a diminutive of senex, an old man.
