Was Justin Martyr in Ephesus?

Greetings,

Some have wondered whether Justin Martyr was ever in
Ephesus. Testimony concerning this matter is given by
Eusebius of Caesarea in his Ecclesiastical History 4.18.6:

"He [Justin] composed also a dialogue against the
Jews, which he held in the city of Ephesus with
Trypho, a most distinguished man among the Hebrews of
that day. In it he shows how the divine grace urged
him on to the doctrine of the faith, and with what
earnestness he had formerly pursued philosophical
studies, and how ardent a search he had made for the
truth."
