What is the other name of the apostle Jude?

Tradition says that Jude Thaddeus, brother of James the Just (James the Greater) was the son of Mary, a cousin of the Virgin Mary, and Cleophas. Cleophas is thought to have been the brother of Saint Joseph. Therefore he would have been a first cousin of Our Lord and, in fact, tradition tells us that Jude and Jesus were quite similar in appearance. As with many cultures today, cousins were often referred to as brothers and sisters. The Epistle of Jude has also been attributed to him, on the basis of the heading "Jude, the servant of Jesus Christ, and brother of James" (Jude 1:1) where "brother of James" is taken as brother of James the Just. Jude was reportedly stoned to death and then beheaded.
The deaths of the apostles are not mentioned in The Bible except for Saint James whose death is mentioned in Acts chapter 12:

"Now at that time, Herod the king laid hands on some of those from the church to harm them. So he executed James the brother of John with a sWord."

Judas, of course, committed suicide so the above statement refers only to the post-Pentecost apostles when Matthias was chosen to take his place.
