Mary Sutton's Death

This document is from my father's collection of family memorabilia and papers. It shows information about Mary Ellison Sutton at the time of her baptism into The Church of Jesus Christ of Latter-day Saints (Mormon), as well as the witness (John Ashcroft—the only one I can find is here, but it's a little difficult to search for someone of that name), the missionary who baptized her (William Houghton—perhaps the father-in-law mentioned in this obituary), and the missionary who confirmed her (John Bradshaw).

The reason I am posting the certificate here, is because in the center of the document, some child of the Suttons (probably Ellen since her certificate is in the same collection) wrote, in pen:

Died Nov 20 1869

Father Died March 4 1865

This is the date that is found in the newspaper notice of Mary's death and which contradicts the information found in New Family Search and elsewhere.
