Thank you for searching. I have found that same info but I was trying to find the document. I have researched births and deaths and found Elalio Perez's death cert in Gomez Palacio, Mexico but not birth record. I also found that the IGI index said his parents were born in San Pedro de la colonias in Coahuila but again I can not find the documents. There were also married in San Pedro in 1880.
