I checked the list I have of the burials in Oak Bowery aka New Bethany Cemetery and did not find any Ezell burial listed.
The cemetery is located at Ellisville, Section 36, Township 8, Range 13West. It appears to be a small cemetery and may not have a sexton now. You may want to check the local newspapers for a mention of Mrs.Ezell's death. Unfortunately death records were not created for many of our ancestors in spite of the law requiring such records.
I suggest that you contact the librarian in Jones County and see if the library has additional sources for your research.
