It would seem the Tonkawas did indeed practice a very dark form of medicine. I do believe disease and combat whittled down their numbers more’n anything tho, the thirty under MaKenzie in the 1870’s being most of what was left of their warriors.
I recall reading mention of the few survivors marrying mostly into the Caddos. FWIW I believe there still is a Tonkawa Tribe existing as a entity in Oklahoma....
