One of the testigos Santiago Dias de 66 Anos Espanol de Oficio Lavrador (¿) de Azogueros. He goes on to give testimony and ends that because he has a relationship that of grandfather (es nieta) does not stop me from telling the truth.
Because I know that his wife is Michaela Gomes, I was able to locate a record of them I had created some time ago. They were parents to Pedro Antonio Dias de Leon (don’t know where the de Leon came from). Which led me to their marriage record that has only his name as Joseph Santiago de Padres no Conocidos and later the dias de leon appears though the first had Santiago, and Antonia had Dias.

Don Joseph Santiago Diaz de Leon 1742– L2VD-WCD cc Dona Michaela Gomez 1746–
