I gathered very little information on the Grijalva name other than the initial identification as Rosalio's second wife. I got stumped at Ruperto Acuna and Luz? so I moved on to another line. I did find out that Luz Acuna's maiden name was Perea and she was the siter of Luz Perez Sanchez that adopted my grandmother after all. I was also told that Luz Acuna had a different first name and that her sister Luz Sanchez was actually the Luz of the family, but I haven't had any luck with that.
