Marcus Livius Drusus
Drusus did adopt Marcus Livius Drusus Claudianus, born Appius Claudius Pulcher. This adopted son married Alfidia, with whom he had a daughter named Livia. This Livia was the famous Empress, the wife to the emperor Augustus and mother of the second emperor Tiberius. Therefore, through the adoption of his son, Marcus Livius Drusus and his family (the Drusi) became eventual ancestors to the imperial Julio-Claudian dynasty.
