Hello again Erlinda,
The three girls you mentioned are the daughters of Aca's son Rudolfo. The youngest was adopted.
Rosella Ponce Padilla is the daughter of Santiago Eustaquio Ponce, one of Santiago's sons. She sent me the photo I mentioned. I have attached it. The one on the left is Santiago Ponce. I am hoping you will recognize the man on the right. I believe it is either Santa Cruz or Porfirio.
Regards, Dave Nelson.
