Lucius Tarquinius
Demaratus' elder son, Lucius, migrated to Rome, where he eventually rose to the throne as Lucius Tarquinius Priscus. After subduing the Latin town of Collatia, Tarquin placed his nephew in charge of the Roman garrison there. Egerius was the father of Lucius Tarquinius Collatinus, one of the first Roman consuls in 509 BC.
