Looking for a Prueba de nobleza y limpieza de sangre

I have connected myself to the Ramirez Cornejo family. I found a mention in Holcombe's papers. One of the sources is

“Prueba de nobleza y limpieza de sangre” made by Cristóbal José Gómez Cornejo, 10 June 1758 in Jalostotitlán, Jalisco

Any idea how to locate this document? Thank you

Alex

I've tried to find a similar document referenced on one of Jaime Holcomb's family group sheets, but with no luck.
