- Marriage: Arviragus King of Siluria 
According to Wurts, in his " Magna Charta ," Claudius had a daughter, Venissa (Venus Julia), but there is no record as to which of Claudius' wives was her mother. This connection has not been confirmed elsewhere and is highly questionable.
Venissa (Genissa, Genvissa, Genuissa), according to Geoffrey of Monmouth 's twelfth century Historia Regum Britanniae , was a daughter of the Roman Emperor Claudius , whom he gave in marriage to the British king Arvirargus once he had submitted to Rome.
According to Geoffrey's account she was very beautiful, and so enchanted Arvirargus that he preferred her company to anyone else's. He founded Gloucester , supposedly named after Claudius, in her honour. When Arvirargus fell out with Rome and Vespasian was sent to enforce a reconciliation, Venissa acted as mediator between them.
