2 Timothy 4:21

Eubulus salutes you, and Pudens, and Linus, and Claudia, and all the brothers.

These final names are probably those of members of the churches in Rome, after which the greetings of the whole church is mentioned (‘all the brothers and sisters’). They are added with him in his final salute. A Linus was later mentioned by Irenaeus as having been a prominent ‘overseer’ (bishop) at Rome.
