This tradition suggests that perhaps the sons of the elder Tarquin attempted to seize power, but were defeated by the regent, Servius Tullius, and his companions; Tullius would then have attempted to end the dynastic struggle by marrying his daughters to the grandsons of Tarquinius Priscus.
Tradisi ini menunjukkan bahwa mungkin anak-anak Tarquin tua berusaha merebut kekuasaan, tetapi dikalahkan oleh bupati, Servius Tullius, dan teman-temannya; Tullius kemudian akan berusaha untuk mengakhiri perjuangan dinasti dengan menikahi anak perempuannya dengan cucu dari Tarquinius Priscus.
