Hi Lindsay Coleman,
Sounds like this has been quite a journey! Good for you.
You asked for tips to identify where she is buried. Some tips and a pretty good clue follow.
(1) Death Certificate
Using the death reporting on her profile (thank you; seems from Ancestry's "North Carolina, Death Collection, 1908-2007"), I checked for available records at FamilySearch. Family History Library Catalog reports they have filmed the North Carolina death certfiticates for this period. Carrie's record has been indexed; reference below suggests her death certificate can be pulled from FHL film 1991943 ("Death certificates no. 7000-9999 v. 07A-09B 1992").
"North Carolina, Deaths, 1931-1994," index, FamilySearch (https://familysearch.org/pal:/MM9.1.1/FG62-PXT : accessed 2014), Carrie Estelle Bartholomew, 07 Feb 1992; citing Clyde, Haywood, North Carolina, v 07B cn 7706, State Department of Archives and History, Raleigh; FHL microfilm 1991943.
FamilySearch's indexed entry reports she was a resident of "Canton, Haywood, N.C." at the time of her death; that she died (event place) at "Clyde, Haywood, North Carolina" and was buried, "Waynesville, N.C." at "Greenhill Cemeter[y]."
(2) Obituaries - Obituaries often contain notice of a funeral and/or gravesite. Obituaries often provide other helpful information.
(3) Church Records. Services were sometimes held at the church or gravesite. The records of these events may provide helpful information.
(4) Cemetery Records. These records ususally specify the location of the burial or memorial, but sometimes contain substantially more information. Note that, especially for women, the name on the death record may not be the same as the name on the burial/memorial plot or gravestone.
(5) Research about other, close family members. Family members are often buried with or near other family members.
Hope this thelps.--GeneJ
