My Great Grandfather and Her Sister Same Name Calistro Madera/Calistra Madera But I can't find his

I have made an extensive search trying to find the baptism record of my Great Grandfather Calistro (Calixto) Madera. But I have found the baptism records of his brothers and sisters. But his I still can't find my Great Grandfather's Baptism Record. But I found a Baptism record of a sister with the same name. This is wierd. His sister, "Calistra Madera" Baptized in 1853 daughter of "Patricio Madera and Dimas De La Paz" Her Paternal Grandparents are Juan Benancio Madera and Geronima Fernandez:
