Indigena-Blanca

my research, searching for my half sibling ancestors at Totatiche Jalisco provided me
with a birth record of her great grandmother. in the sentence indicating raza, it had Indigena-Blanca. does it mean that she was a mestiza? Other findings I have founded were either Indios/as, mestizos/as or espanol/a natural if born in Nueva Galicia, so the term indigena-blanca is new to me. Can anybody clear this for me. Thanks. Arturo
