Los Altos -Mulatos ??

Hola Linda , I understand that the Espanoles kept to themselves but by looking at the records ,there are tons of Mulatos to the point( I think) there could of been some Mulato Groups/colonies/Individuals still around, It looks like they were magicians and went poof,gone . For in example :I was told by a distant relative who lived in El Rancho del Refugio (between San Miguel el Alto, San Jose de Los Reynoso and San Julian area(Jalisco),that a Rancho named La Puerta del Sauz(de Ramirez) that there 200 Slaves housed/lived there. I believe it was probably around 1800 give or take a few years. Well I still ponder where did these guys go or what happened to them. I don' t know ,maybe they just inter married I guess.
