Aristobulus in Britain?

"Peter preached the first missionary sermon to representatives of at least thirteen different sections of the known world. Acts 2:9 Parthians, and Medes, and Elamites, and the dwellers in Mesopotamia...–from the north-east are mentioned. Arabians had come from the south-west. Asia Minor to the north was represented by Jews and proselytes from Phrygia and Pamphylia, Cappadocia, Pontus, and Asia. There were pilgrims from Crete in the Mediterranean Sea, from Libya and Egypt in North Africa, and even strangers from Rome, the center of the Empire. Three thousands souls responded to that first appeal, and during the following days thousands more accepted the message of the Gospel. As these separated after the feast and returned to their various homes, they carried with them the good news of salvation, and began to raise up churches in the very uttermost parts of the Empire.

In the 13th chapter of Acts we find that Antioch, the Graeco-Syrian capital of the East, had become a center from which evangelists were being sent forth into the regions beyond, along the great trade routes which radiated in all directions from that city. Paul, Barnabas, and John Mark received their commissions, under God, from the church at Antioch and spread the message over Asia, Greece, Macedonia, and southern Europe as far as Rome, and perhaps even farther afield. In the second century Alexandria became another center from whence proceeded missionary pioneers into all the earth. It is not, therefore, unreasonable to suppose that some of these fervent Christian missionaries penetrated the forests of Gaul, found themselves on the shores of the narrow channel which separated the wild islands of the Brittani from the mainland, and crossed over to carry the good news of salvation there also.

There are many legends and traditions which suggest different leaders of the early church as the pioneers of the Gospel in Britain.
....group of ancient records identify the Christian worker Aristobulus, whose family is mentioned by Paul in his letter to the Romans,

[Salute Apelles approved in Christ. Salute them which are of Aristobulus' household. Romans 16:10] as one of the pioneers of the Gospel in Britain. Thus The Menologies [Martyrologies] of the Greek Church state: Aristobulus was one of the seventy disciples, and a follower of Paul the apostle, with whom he preached the Gospel to the whole world, and ministered to him. He was chosen by Paul to be the missionary bishop to the land of Britain, inhabited by a very war like and fierce race, by whom he was often scourged and repeatedly dragged as a criminal through their towns. Yet he converted many of them to Christianity; and after he had built churches and ordained deacons and priests for the island, he was there martyred."
