This may or may not help you, but thought I would send the info. Familysearch.org also has an index of the Alabama Deaths, 1908-1974 on its site.Sometimes it gives more info than the Ancestry.com index (and FamilySearch is free!). The Familysearch.org site shows that James Clearance Rivers died on Feb. 17, 1932. His parents were James E. Rivers and Jane Sonell.(Note: I have found that their transcriptions are full of human errors, like all sites that depend on volunteers to transcribe their records.)
It also shows that Marietta Greene Rivers died on April 4, 1950 in Jefferson County, AL. Her parents are shown as George Washington Greene and Sarah Hairston. Her death certificate number is 7469.
Unfortunately, these 2 records do not show the cemetery they were buried in.Some records on this site do.
Hope this helps a litte.You can always contact the genealogy department at Wallace State Community College (in the Library) and request a copy of their death certificates.They should show the cemetery on them.
