My ggrandfather's sister was Mary Elizabeth (Morris) Hines Bixby (born in Valparaiso, IN in 1859), wife of George Bixby, brother of Tams Bixby Sr. They moved from Stillwater, Minnesota to Muskogee in 1899. George and Tams operated the newspaper in Muskogee and Oklahoma City. Tams headed up the Dawes Commission in 1906 that created the State of Oklahoma. Lizzie's son by her first marriage, Charles Floyd Hines married and lived in Wagoner.
There are some stories about her brother, Charles P. Morris, who is believed to also have lived in Muskogee, Indian Territory for a time. His wife was Jennie (McNulty) Morris who he married in Chicago in 1879. They had two children, Virginia Rebecca "Jennie" Morris in 1883 and Clara Louise "Lulu" Morris in 1892.
Letter from Robert Morris Brown, dated Oct 27, 1985. ". . . My mother was Clara Louise (Lou/Lulu) Morris Brown Trevor. The younger daughter of Charles Morris, born May 3, 1893 [actually 1892] Indian Territory. Her mother [Jennie (McNulty) Morris] died when she was fourteen months old and was legally adopted when she was sixteen months old by her paternal uncle, Joseph Dexter Morris and his wife of Kirkland,Illinois. . . . "
Letter from Robert Morris Brown, dated Nov 15, 1985. ". . . The sisters [lou and Jennie] with their father [Charles] were visiting their grandmother [Rebecca] in Valparaiso - also the J.D. Morrises with their two children - Clara Rebecca [b. 14 Feb 1880] and Virginia Morris [b. Apr 1883] were the same age - Joe was four or five years older [b. 25 Oct 1877] - he was about 14 or 15 [age 15 on 14 Feb 1893] at the time. It was the 14th of February  - Clara's birthday - Joe suggested that the baby be given to Clara for a birthday present - that started the ball rolling for the adoption of my mother [age 9 mos. on 14 Feb 1893]. . . ."
Letter from Robert Morris Brown, dated Dec 18, 1985. ". . . I have before me a picture of my blood grandmother [Jennie (McNulty) Morris] - a most striking woman - this is a copy of the original - she died on her grant (land) around 1895 of Typhoid Fever. The story goes that both girls were left in care of friendly Indians while their father (Charles) and their maternal grandfather drove via wagon into Muscogee for a coffin and to report her death! I once had a picture of Jennie (about 10 years old) the maternal grandfather sitting holding the the baby which was my mother - this picture was made in Muscogee - name of studio and town was printed at bottom of picture - here are two incidents that indicates that Muscogee was nearby. The reporting of the death of Charles's wife and the picture of Jennie, my mother, and their maternal grandfather. . ."
Morris Brown died and the pictures have disappeared.
Another story from another line of the family states that Charles P. Morris was a Marshal in Muskogee.
I am trying to determine if any or all of these stories are true and have not had any luck searching the internet. There should be a record of the death of Jennie Morris in between 1892 and 1895 of typhoid in Muskogee; there might be a record of "grant land" in Muskogee, She was a famous horsewoman who rode in the Famous Cimarron (whatever that means); There might be a record of Jennie's father "McNulty" there; There should be a record of Charles Morris as a Marshal in the area. I am not sure where to begin.
