First the grand-daughter must a daughter's daughter, not a son's daughter.
If she isn't mtDNA on her will not be the lineage you want. If she isn't is
there a great granddaughter or greatgrandson who has only females between
him/herself and your great-grandmother? Grandsons & greatgrandsons can donate mtDNA
if their mother is in an all female line from the Great-grandmother.
Then you must have a docuemented relationship between the person tested, the
greatgrandmother and yourself. Sounds to me as if you do, so this shouldn't
be a problem.
Now the big "hump" is that your great-grandmother could have been Native
American from both her mother and father's lineages, or only one. And then she
could have been Native American on only part of those two lineages. In short,
ONLY if she is Native American from her mother's mother will it show up on the
test. mtDNA will test the (a)/(b)/(c) lineage only.
(c) Mother's Mother Mother's Father Father's Mother
(b) Mother Father
(a) Great Grandmother
Sons and Daughters of the daughter(s)
If your great grandmother's mother's father and her fathers parents were all
Native American, but the line you test was NOT, then you won't find Native
American in the mtDNA you propose testing. However, you MIGHT be able to
verify Native American ancestry from other "input lineages" by testing other
descendants, say your great grandmother's aunt on her father's side would carry the
father's mother's DNA -- if you can locate an all female lineage from her, you
could get that mtDNA. And so on.
