Mary of Clopas

Wife of Alphaeus
Mother of James the Younger/Less

The Bible does not name Mary of Clopas until the crucifixion

Mark 15:40There were also women looking on afar off: among whom was Mary Magdalene, and Mary the mother of James the less and of Joses, and Salome;

Mark 15:46-47
46 And he bought fine linen, and took him down, and wrapped him in the linen, and laid him in a sepulchre which was hewn out of a rock, and rolled a stone unto the door of the sepulchre.
47 And Mary Magdalene and Mary the mother of Joses beheld where he was laid.

Matthew 27:54-56
54 Now when the centurion, and they that were with him, watching Jesus, saw the earthquake, and those things that were done, they feared greatly, saying, Truly this was the Son of God.
55 And many women were there beholding afar off, which followed Jesus from Galilee, ministering unto him:
56 Among which was Mary Magdalene, and Mary the mother of James and Joses, and the mother of Zebedees children.

Matthew 28:1-9
In the end of the sabbath, as it began to dawn toward the first day of the week, came Mary Magdalene and the other Mary to see the sepulchre.
2 And, behold, there was a great earthquake: for the angel of the Lord descended from heaven, and came and rolled back the stone from the door, and sat upon it.
3 His countenance was like lightning, and his raiment white as snow:
4 And for fear of him the keepers did shake, and became as dead men.
5 And the angel answered and said unto the women, Fear not ye: for I know that ye seek Jesus, which was crucified.
6 He is not here: for he is risen, as he said. Come, see the place where the Lord lay.
7 And go quickly, and tell his disciples that he is risen from the dead; and, behold, he goeth before you into Galilee; there shall ye see him: lo, I have told you.
8 And they departed quickly from the sepulchre with fear and great joy; and did run to bring his disciples word.
9 And as they went to tell his disciples, behold, Jesus met them, saying, All hail. And they came and held him by the feet, and worshipped him.

Though little is spoken of her we do know that Mary, her husband Alphaeus, and her son James were devoted followers of Jesus. How do we know? James was one of the 12 selected by Jesus to be his one of his apostles, and she kept company with Mary Magdalene.
