Pima Bajo people
They are related to the Pima and Tohono O’odham of Arizona and northern Sonora, speaking a similar but distinct language.[5] Major communities in the Pima Bajo region include Maycoba [es] and Yécora on the Sonoran side of the line, Yepáchic on the Chihuahuan.All three of these communities were almost exclusively Pima in the 19th century, but in recent decades many mainstream Mexicans from the lowlands have migrated into the area.The Pima were also converted to Christianity early in the Spanish period, and most of them still practice an antiquated, almost medieval, form of Catholicism introduced by the Jesuit missionaries.[8] Holidays, especially Holy Week (Semana Santa) involve elaborate ceremonies and celebrations reflecting the form of Catholicism practiced by the Pima.
