Where does it say that John Mark went to Rome with Peter?

The association of John Mark with Peter in Rome is implied in several early Christian writings rather than explicitly stated in the New Testament. Early church tradition, particularly noted by Church Fathers like Papias and later by Eusebius, suggests that Mark served as Peter's interpreter and that his Gospel was based on Peter's teachings. Additionally, 1 Peter 5:13 mentions "she who is in Babylon," which many scholars interpret as a reference to the church in Rome, and John Mark is traditionally linked to this community.
