I don't see a correct corresponding category for the cemetery. Roselawn Memorial Park According to the FindAGrave site, it is called several names. None of those names include the name Roselawn Memorial Park Cemetery. It is in Carter County, Tennessee (no town designation) and should not be confused with the category already created of Roselawn Memorial Gardens in Murfreesboro, Tennessee (different county).
While you are waiting for help creating the category, I've added the death place as a location to the profile. It would be worthwhile to locate a source that states where she is to be buried since the FindAGrave link for Mary Phipps has no image.
