An important descent group of the late Etruscan period, principally from the Volterra area, but also known with slight variations in Orvieto, Orte, Castiglione del Lago, Tarquinia, and Bologna from as early as the fifth century BC. The name survived in the form Caecina in the Roman period and provides one measure of the process of Romanization in North Etruria.
