Lorenzo Alvarez y Josepha Alvarez

Hola Members y Primos, I believe I have figured out who or which Lorenzo Alvarez I was Investigating. In the second marriage of Lorenzo Alvarez to Gertrudis Efigenia Ramirez de Ramirez ,the Padrinos were Francisco Enriquez and Ana Alvarez(daughter of Francisco Alvarez Tostado and Ana Ramirez de Mendoza. This couple was also padrinos to Lorenzo Alvarez's daughter(Juana Josepha Alvarez) of his first marriage to Josepha Alvarez. The conclusion I have made that Lorenzo Alvarez and Ana Alvarez are siblings.
I still can't figure out who Josepha Alvarez's parents were.
