Note 2 at Acts 23:16: This is one of the few times Paul's family is mentioned in scripture. It appears that Paul's nephew had received salvation through Jesus. At least he was not hostile towards it as the non believing Jews were.

Also in Romans 16, Paul mentions a number of his kinsmen. He specifically mentions Andronicus and Junia who were born again before Paul (Rom. 16:7), and were also imprisoned for their faith in Christ.

Herodion was also a relative of Paul who was one of the believers in Rome (Rom. 16:11). In Romans 16:13, Paul salutes Rufus and states that Rufus' mother was his mother also. This could be speaking figuratively or this could literally be a reference to Paul's mother and brother Rufus as believers.

In Rom. 16:21, Paul uses the word "kinsmen" after listing several men. It is not clear which of these men he was referring to as his kinsmen.
