Jude the Apostle
The historian, Bishop Eusebius of Caesarea, quotes the earlier chronicler, Hegesippus, who wrote, c. AD 180, that he had years before interviewed the grandsons of Jude the Apostle and learned that Clopas was the brother of Joseph, husband of the Virgin Mary: "After the martyrdom of James, it was unanimously decided that Simeon, son of Clopas, was worthy to occupy the see of Jerusalem. He was, it is said, a cousin of the Saviour." Hegesippus noted that Clopas was a brother of Joseph. Epiphanius adds that Joseph and Cleopas were brothers, sons of "Jacob, surnamed Panther."
