Quem people
The Quem people were a group of American Indians that settled along both banks of the Rio Grande in what is now Texas, United States and Coahuila, Mexico. They are known to have settled around present-day Eagle Pass and Piedras Negras. Damián Massanet also recorded them, in 1691, as one of six groups of Indians encountered along a stream called "Caramanchel"; this appears to correspond with today's Comanche Creek in the southwestern part of Zavala County. Massenet implied that all six groups spoke a language now known as Coahuilteco.
