Jacob "Doc" Sturm.
Perhaps originally a Texas German missionary type?
Born 1825, by age twenty-two a doctor and agriculturalist among the Comanches on the Brazos Reservation. Twenty years later he's still with them, even after the hellish Civil War years.
No word on wife or children until 1877 when he was fifty two years old.
At that time his eighteen year-old Caddo wife bore him the first of at least five children, two sons and three daughters, four of whom in turn lived into their eighties.

Doc Sturm Dead
Dr. J.J. Sturm who lived for many years on Cobb creek, north of the present town of Fort Cobb, died last week as the result of a wound in the arm caused by the accidental discharge of a shotgun.
Doctor Sturm had lived longer among the Indians in this section than any other white man, and in the early days his place on the lakes at Cobb creek was known far and wide.
He was a most interesting conversationalist, and a kind hearted generous man. I'm guessing there's a real story somewhere in all of this.
