His father was Titus Menenius Lanatus, consul in 477 BC.
[1] Menenius was one of three patricians sent to lead the colonization of Ardea by the orders of the consuls Marcus Fabius Vibulanus and Postumus Aebutius Helva Cornicen in 442 BC.
The two other members of the triumviri coloniae deducendae were Titus Cloelius Siculus and Marcus Aebutius Helva.
[2][3][4] In 439 BC Menenius was elected consul together with the elderly Titus Quinctius Capitolinus Barbatus.
The year saw a large conspiracy led by Spurius Maelius and the appointment of Lucius Quinctius Cincinnatus as dictator for a second and final time.
