Mary Winchester has a grave erected for her in Greenville, Illinois.Sam initially wants to pay his respects, but Dean is reluctant to allow him.
In "Alpha and Omega", Dean and Sam visit Mary's grave, presumably the same one, to pay their respects in case the world ends, and Dean's mission fails. Dean had hoped to be interred next to her.
- Mary's unnamed uncle is only mentioned once. He was presumably killed by Azazel, as many close relatives were targeted after Mary's death.
