Magnificent image Perico! I am glad you posted it here! I agree people sometimes use photographs for their own questionable puposes. I once found my own paintings on a Belgian website of supporter of a racist political party! As for Eskinya, I recall he indeed was shot and killed, by Naiche, while Taza wounded Pionesanay, I just was wondering perhaps he did somehow survive... but more likely this is another individual, perhaps a son or other relative?
I think the women above and slightly to the left of Nana could be: chief Chihuahua wife Ilth goz ey (Il Gazie) to her left Jolsanny's (Ulzana) wife Neschilla, left of her Il Gazie's sister and second wife to Chihuahua and to the left of her Nahn-ish-Klah wife of jolsanny.
