Also, how long did Mary live after Jesus was crucified?
11 years
Furthermore, did Mary Mother of Jesus go to the tomb? The other gospels give various indications about the number and identity of women visiting the tomb: John 20:1 mentions only Mary Magdalene, but has her use the plural, saying: "We do not know where they have laid him" (John 20:2). Matthew 28:1 says that Mary Magdalene and "the other Mary" went to see the tomb.
Keeping this in consideration, how and when did Mary the Mother of Jesus die?
Tradition would have us believe she died peacefully a natural death. Where did she die? No one knows, or it was kept a secret. The Council of Ephesus (431) decided she must have died in Jerusalem, but an alternative tradition has it she died in a village on the outskirts of Ephesus.
