Have 25 yrs of Baja California genealogy research to share-particularly interested in pre-1850 families. My personal lines are: MARRON (1750-1900), CARRILLO (pre-1840), MILLAN (1720), and MAYORAL (1750-1840). These people lived in Baja Sur. These are ancestors of those of the same name in my family who lived in northern Baja late 1800s.
