And who knows right? Mary was so insignificant at the time there wasn't even one writer, either secular or religious who even cared enough to keep track of where she lived or spent her last days. Nobody knows where she lived, where she died, or where she was buried. Even the apostles themselves never again even mentioned her.
she was probably assumed into Heaven by then...after all, would the Apostles have been so crass as to ignore her if she was there????....
