Family and Tradition
According to tradition the two were children of the Apostle Alphaeus, a figure associated with Capernaum in Galilee. The Gospels name an Alphaeus as father of the Apostle Matthew and of the Apostle James the Less, and some have further identified him with Cleopas, though the sources do not state these connections with certainty. The claim that Abercius and Helen were children of this Alphaeus has been questioned by some, and the relationship is not regarded as definitively established.
Little else of their lives is recorded. The two are remembered jointly as a named sibling pair, and the tradition concerning them centers on their confession of Christ and their martyrdom rather than on any extended biography.
