I have been researching my wife's family along the Morin surname and have traced them back to the Mission de San Francisco de Coahuila de Nuevo Tlaxcala and the Mission San Miguel de Aguayo in Monclova, Coahuila. Their caste is listed as indio and indio-Tlaxcaltec. I would like to hear from any one who researching this Morin branch. Thanks, Dwain
