Thank you. I did find the cemetery listings, and I think they are the right ones. The 1900 census says John was born in 1826 and Mary was born in 1836. the headstones have different ages.
Mary had a daughter, Louisa Trusty (married name) who had a son Leon.
John and Mary had a son William, born 1868 in Illinois. John Collins owned and operated a boarding house in Ponca City in 1900, where he lived with his family. After 1907, the death of Mary, the whole family seems to disappear from the face of the earth. I found William's son, clyde later, I cannot find where Louisa, her son, or her half-brother william disappeared to.
