Their parents names weren't on this document.
Since she last lived in Ionia, Jewell, Kansas, I'd look there for her death. I don't believe that Kansas was using death records that early in time. I'd do a Google search for Jewell County Kansas Genealogical & Historical Society. Then I'd contact them and ask if they have a local death index, indexed newspaper death notices and inventoried cemeteries. Successful Searching!
