"[2][3][1] Like his father, Lucius Tarquinius married an Etruscan noblewoman, but as the son of a foreigner he was unable to attain high station at Tarquinii.
[13][14] After a long and prosperous reign, Tullius was deposed by his own son-in-law, Lucius Tarquinius Superbus, the son or grandson of the elder Tarquin.
[25][26] Meanwhile, the first two consuls were each descendants of Demaratus; Brutus' mother was the king's sister,[27][28] while his colleague was Lucius Tarquinius Collatinus, the son of Egerius, and husband of Lucretia.
[29][30] Before his death at the hands of Arruns Tarquinius, Brutus compelled his colleague to resign and go into exile, arguing that none of the Tarquinian gens should hold power at Rome.
[31][32] Three important Roman gentes claimed descent from Demaratus; the Junii, through the first consul; the Mamilii, who came to Rome from Tusculum in the fifth century BC; and the Tullii, through Servius Tullius.
