(a loanword from Spanish)
the surnames of a cacique family that was active in the distribution (and probably the production) of títulos of the type called Techialoyan, along with false genealogies and coats of arms; the name Austria was also typically a part of the string of last names used by this family
For more information on this family, see the book by Maria Castañeda de la Paz, Verdades y mentiras en torno a don Diego de Mendoza Austria Moctezuma (México: Universidad Nacional Autónoma de México, 2017).
