|Three Marys, one of whom is Joanna, with tomb-myrrh|
Luke tells it like this in Chapter 24 -- 9 When they came back from the tomb, they told all these things to the Eleven and to all the others. 10 It was Mary Magdalene, Joanna, Mary the mother of James, and the others with them who told this to the apostles. 11 But they did not believe the women, because their words seemed to them like nonsense.
Mark tells it like this in Chapter 16:1 -- And when the sabbath was past, Mary Magdalene, and Mary the mother of James, and Salome, had bought sweet spices, that they might come and anoint him. Mark also says that the apostles did not believe Mary M. when she told them about it.
|Shrine of Joanna, with more myrrh|
Even if Matthew's right and there were only two women, they might have gathered other women before they reached the apostles. Luke implies more than three, referring to "the others with them. Mark has three, no more nor fewer, but again, that doesn't mean they didn't gather others on the way. It also doesn't mean that Salome, who is sometimes called Mary to make it three-of-a-kind, could not also be called Joanna. Or Jessica.
There's a story outside the Gospels about Saint Joanna that definitely bolsters her saintly status. As the wife of Chuza, Herod's steward, she had some pull in the palace. She used that influence to get the head of John the Baptist so that she could ensure that it was decently buried.
