A Descendant of Peter the Apostle?

Twelver Shiahs, who comprise about eighty-five percent of all Shiah Muslims, believe that Bibi Narjis Khatun, a female descendant in her maternal line of Jesus’ disciple, Saint Peter, became the wife of the 11^th Imam Hasan al-Askari.  A son of this marriage, Muhammad al-Mahdi, became the 12th and final Imam.  (Other traditions say that Narjis was a Byzantine slave or a black African slave.  She may have been of Persian and/or Roman descent.  If descended from Peter, she was, by Jewish tradition, Jewish.)

There probably is no way to prove historically that Narjis was a descendant of Peter.  Since Peter probably had children, it is, at least, possible.

Clearly, Peter and the other disciples of Jesus were married, as would be entirely normal for Jewish men of the biblical period.  The Bible plainly says that Peter was married. (Matthew 8:14, Mark 1:29-31, Luke 4:38-39, and 1 Corinthians 9:5)  Clement of Alexandria (Stromata, III, vi, ed, Dindorf, II, 276) said that Peter had children as did Philip, and probably Paul.

Ignatius of Antioch, in The Epistle of Ignatius to the Philadelphians, chapter 4, verse 30, said  “… of Peter, and Paul, and the rest of the apostles, that were married men. “  Ignatius, the Bishop of Antioch, was in a position to know this because he was trained as a student by the Apostle John.
