Hello…does anyone know where I can get more info regarding Reales?
I’m going through 1780 archives, and I’m coming up with towns called Real de (fill in blank). Many are now towns such as Real de La Yesca (where I’m presently researching) or Real de Bolaños. I can’t seem to find Real de El Carrizal or Real de San Raphael.
I am noticing priests distinguishing between ciudades, pueblos, ranchos & haciendas.
Anyone know of a website or book that can fill me in?’

Cheers,
Andelmo
