It is Jewish practice, presumably going back to Apostolic times (the period of the Talmud) that one minimizes the visits to a loved one's grave during the first year. Additionally, Mary, as a devout Jew, would have been observing shiva, a full week of mourning in which the immediate family of the deceased stay home, abstain from any creature comforts (such as music or perfume), and go without shoes (shoes being regarded as a sign of comfort and prosperity). [see, for example, chapter 42 of Rabbi Chaim Binyamin Goldberg, Mourning in Halachah, publ. 1991 by Mesorah Publishing] Mary might have been observing shiva or, being considerably older and perhaps more griefstricken than the other women, was not among the first to reach the tomb.
As for the part of the inscription that was thought more ancient than the rest, "Jesus son of Joseph" (keeping in mind that Jesus is the Greek equivalent of Joshua) is about as common as "Robert son of William" would be nowadays.
BALONEY!!!!!
Then why did Mary Magdelene, Joanna, Salome, and Mary (the mother of James & Joses) all disciples of Jesus Christ, go to the tomb IMMEDIATELY?
Lame "rebuttals" like that do not help your cause.
