Hi,
I didn't find anything else about her. I looked for a marriage in Ancestry and FamilySearch but didn't find one in Muskogee County.
Oklahoma doesn't publish their death dates and they're not open to public inspection (for more info go to
www.ok.gov/health/Birth_and_Death_certificates/Death_Certifi...). She might have died in Muskogee County.
You can do a Google search for Muskogee County Oklahoma Cemeteries and look for her in the inventoried cemeteries.
Sometimes in Oklahoma the local genealogical society will create their own death index. You can contact the Muskogee County Genealogical Society,
www.okgenweb.org/~mcgs/research.htm. Successful Searching!
