If you compare that with the reference to another Mary at the foot of the cross in Mark 15, with a similar name list of children, you will recognize that “brothers” there are simply “members of the same household that are close in age”.

All three Marys, Mary the mother of God, Mary the wife of Cleophas and Mary Magdalen were at the scene of the Crucifixion; Mary the Mother of God was at the foot of the Cross and the other two were “afar”. James and Joses however are identified as children of Mary Cleophas. (Mark 15:40, John 19:25).
