Doing research on my Grijalva family. At present I am trying to find out info on Joaquin Grijalva who married Maria Rivas and had a son by the name of Rafael Grijalva who later married Rosalia Estrada who had Rafael and Louis or Luis Grijalva (my Gfather). I have info on the latter two, my Grandfather and his brother Rafael but I am working my way back. If anyone can share info on where I may find resources on searching pretty far back (late 1700's and early 1800's) I would appreciate an email and thank you beforehand. I am posting this message for the Sonora, Mexico area. Again thank you. Gloria.
