Hello
Tarahumara on your family tree?
Below is a link fra the Informacion Matrimonial for Ojo Caliente in Zacatecas (1794 - 96). The person named in the documenent is named as a cacique and as the the son of Tarahumara caciques.
The name looks like Augustin Ynchaurregui but I am not sure. His coming wife has the last name Montellano. images 297- 299 and the date is 23 Dec 1795.
Its not often that there is any information about ethnic affiliation beyond caste, therefore I thought I would share this. The name Ynchaurregui is Basque.
