Mary does not fit the details of the verses in Rev 12. She is not on earth, the location of the pursuit. The woman is.
Only the LORD or an Apostle can correctly interpret Revelation for us. My view is there is only one mother of the Messiah, Miriam, who is also Israel, who is also the Church. That unity will never be broken. No one can separate her from Messiah, from Israel, or from the holy catholic apostolic church (not that they won't try).
