Miramontes connection

Lorenso De Miramontes and Maria De Santiago had a son, Ysidro De Miramontes who married Bernarda De Avila 21 Jan 1709. Brigida De Miramontes who married Rafael Pinto De Avila 23 Jan 1735 was the padrina. This is my Avila connection to the Miramontes family and I wonder if anyone can provide information or assist me. Thank you. Evie
