Herodian dynasty
Although the names of his parents are unknown, it is known that Philo came from a family which was noble, honourable and wealthy. It was either his father or paternal grandfather who was granted Roman citizenship from Roman dictator Gaius Julius Caesar. Jerome wrote that Philo came "de genere sacerdotum" (from a priestly family). His ancestors and family had social ties and connections to the priesthood in Judea, the Hasmonean dynasty, the Herodian dynasty and the Julio-Claudian dynasty in Rome.
