Ninil
Niñil lies in the wooded highlands west of the Valley of Toluca, in a region long inhabited by Mazahua communities. During the sixteenth century Franciscan missionaries worked among the peoples of Matlatzinco and the Mazahua country; Andrés de Castro learned Indigenous languages for this work. A church dedicated to Our Lady of Mercy later became a focus for settlement at Las Llaves, in the country associated with Niñil.
