Latin names around a counter-cultural Paul

In an 'eye-witness account' of 'going to church in the first century' we hear from one 'Publius Valerius Amicius Rufus'. He was visiting Rome from Philippi. There is indeed a Publius Valerius Rufus of Philippi, attested in a Roman inscription, but a century later (AD 144). The additional cogomen (Amicius) is in any case improbable. Yet it was right to have taken the Rufus whose mother protected Paul (Rom 16:13) as a Roman citizen. It was a historically dignified name. And there are far too many Latin names around St Paul for them to be explained mostly as loan-words domesticated into the Greek namestock.
