Garza language
Garza is an extinct Pakawan language of Texas and Mexico. It is known from two tribal names and twenty-one words recorded from the chief of the Garza by Jean-Louis Berlandier in 1828 (Berlandier et al. 1828–1829, 1850: 143–144). At that time, the Garza all spoke Spanish and were acculturated. The Garza may have been the same as the Atanguaypacam tribe (of the Comecrudo) recorded in 1748. The Garza were called something like Meacknan or Miákan by the neighboring Cotoname (Gatschet 1886: 54) while they called the Cotoname Yué. Garza is Spanish for "heron." References
