these usually give some destinations.
2) do you have her death certificate? that would help you. how about an obituary. see your local public library for that, interlibrary loan program. this might also help you with historical newspapers around that time. many are on microfilm and can to lent to your library.
3) have you contacted the choctaw and chickasaw tribes directly about any licensing as a teacher or doctor? how about the state of oklahoma. oklahoma became a state in 1907.
you are on the choctaw website, so i won’t give you that one.
do you have a particular school where she taught?
search for that on the internet. or ask the oklahoma historical society.
