Houses of the Rome

Alba Longa

The genealogy of Alba Longa shows how Romulus was the descendant of Aeneas from the royal house of Troy (Dardanian line). Romulus was the founder of Rome.

The founder of the city of Alba Longa, in Latium, was Ascanius or Iulus, the son of Aeneas.

All of Aeneas' descendants, after his grandson Silvius (2nd king of Alba Longa), had the family name of Silvius.

Monarchy of Rome

Unlike most kingdoms in other parts of the world, where the monarchy or the kingship was hereditary, through nobility, in Rome the king was elected by voting in an election from candidates. Therefore a son or close kin didn't necessary succeed his father to the kingship.

It was not even an essential requirement to be a pure Roman citizen to be a candidate for kingship. Most of the kings were of foreign background, such as from the Latin, Sabine or Etruscan cities.

Numa's grandson, Ancus Marcius, did become king of Rome, but Ancus ruled after the Roman king, Tullus Hostilius. Similarly, Lucius Tarquinius Superbus didn't immediately succeed his father Lucius Tarquinius Priscus, but after Servius Tullius.
