Diego Ruiz-Nunes and Catalina or Luisa Catalinia Delgadillo

I've advanced my Ruiz line to Diego Ruiz-Nunes, md to Luisa or Catalina
Delgadillo, by way of their son, also Diego Ruz-Nunes and his wife, Anna
Gonzalez de Hermosillo, natural daughter of Pedro Gutierrez de Hermosillo.
Two of Diego and Anna's four children that I have identified where
baptized in Cuquio, Jalisco: Blas b. 6 Feb, 1676, md to 23 Jan 1718 in
Cuquio to Catharina de Lisarde; Diego b 15 Sep 1691. Their other two
children are Cayatano who md Juana Rovalcaba Estrada in Cuquio 4 Feb 1712,
and Paula, who md Melchor Rubalcaba y Rodriguez de Frias.

My sources are my research on familysearch.com and Retonos de la Nueva
Galicia, Tomo VII, p 179.

I have no idea where Diego Ruiz-Nunes and Luisa or Catalina Delgadillo
live. They probably were born mid1600s. Anyone else researching this
family?

I would appreciate any assistance or suggestions anyone might have.

Thank you.
