I don't have any info for you, mu husband's family was also from Santa Rosalia/Camargo. They lived in the 1800's, Agustin "de la cruz?" Dominguez 1852-1941. He got tired of the Apache indians raiding their town, he and a cousin (cousin killed by Apache) walked out of their town one day, at age 14. Agustin ended up in TX, an elderly man took him in, he stayed with the man (childless) and inherited his store and wealth. Agustin's parents were Vidal Dominguez we believe 1/2 Apache and wife Modela "Maria" de la cruz? Montes. Two trees on ancestry.com with Agustin in them....just kind of searching the Santa Rosalia area, you never know how or who you could be related to from there.
