I'm trying to locate the burial site of my great grand aunt. I have her death certificate, but it does not include a burial location.

Her name was Mabel Olsen Stinson. She died of pernicious anemia at Charity Hospital in New Orleans on the 31st of January 1925. She was born in Norway in 1879.

Not sure how to find her grave. Would appreciate any help I can get.

Thank you.
