Yolanda,
Sorry it has taken me so long to do the lookup for you but here it is.
I have taken the following excerpts from Jose Luis's book relating to Juan Yñiguez. I don't believe he is the one you are looking for because the dates and the wife's name don't coincide but just to be on the safe side I have noted all the pages with Juan Yñiguez and the facts pertaining to each page.
Page 73: Juan Yñiguez, married to Maria Melchora de los Reyes, padron de año 1649, hijo de Juan Yñiguez y Andrea Cortes.
Page 73: In 1628, Ana de Santiago, hija de Juan Iñiguez y Andrea Cortez se caso con Nicolas Estrada, hijo de Xacome Xinoves (Yñiguez) y de Maria de Estrada.
