Nathanael didn't know Jesus even though their towns were five miles apart, and that Jesus was the only one asked for a stranger's tax with the fish-coin miracle. This tells me that Joseph the carpenter died when Jesus was young and whoever it was that took care of Jesus had him away a lot. At the crucifixion, Joseph of Arimathea claimed Jesus's body when every other disciple fled showing he was related to Jesus and must have been his guardian from when he was younger. A look at the history of Christianity shows Britain developed just about as fast as the places near Jerusalem. Looking at the history of southern England establishes that the Phoenicians had voyaged to England to mine for tin in their whole history so the route was well established. Dan had ships, they learned the tin routes from the Phoenicians making the connection to Israel and Judea, and therefore later to Joseph. Many artifacts show than a boy and his uncle are the ones that spread Christianity in that area even before the ministry in Jerusalem. Everyone knows that Jesus was mostly gone from history as a boy, it's easy to see where he was and how Britain got a huge jump on the teachings of Christ.
...nor indeed is it mentioned in any historical sources until the legend appears in the works of French poets. Nor do any of the early church historians make any mention of JoA's myth.
Tertullian says around 200AD that Christianity was well-established in Britain. It was spread there somehow.
Jesus was not teaching until he was baptized by John the Baptist - not before. No jumps here excepts leaps in logic.

Then Tertullian is no help - rgumentum ex silentio. Tertullian does not speak of JoA
