I have recently found the death certificate of my grandmother's sister. She was born Dora Robertson 1889 in Comanche County. She married a man named Tankersley and homesteaded in New Mexico and had a son named William, then divorced Tankersley. My family said she then married a man named King or Keene, had a son named Dugan, and ran a boarding house in Burkburnett. I found her death certificate for 1951 in Cherokee County under the name Cain which showed she had been in the Rusk State Hospital since 1919 from Burkburnett. Do you know anything about any Dugan Cain or stories about things like this?
