Tehuetzquiti.

As published in Wikipedia, this ruler's personal name glyph in the Codex Aubin shows a smiling mouth with fangs. See: https://en.wikipedia.org/wiki/Diego_de_San_Francisco_Tehuetzquititzin#/m.... A very similar glyph appears in a copy made by Karl H. Berendt (copyist)and scanned by the Mesoamerican Language Texts Digitization Project. This second one appears in Wikipédia, https://pt.wikipedia.org/wiki/Diego_de_San_Francisco_Tehuetzquititzin. Finally, a similar mouth appears in two glyphs in the Visual Lexicon of Aztec Hieroglyphs under the title Huetzquiz. These come from the Matrícula de Huexotzinco ff. 529r and 666r.

One Tehuetzquiti was: don Diego Tehuetzquiti, said to have been the fifteenth ruler of Tenochtitlan (central Mexico, sixteenth century)

Another Tehuetzquiti was: don Diego de San Francisco Tehuetzquititzin; husband of doña María, his first cousin, who was the daughter of the lord Huehue Mauhcaxochitzin, fifth son of Tizocicatzin, ruler of Tenochtitlan; don Diego and doña María had children: Ixcuinantzin, Tezcatl Popocatzin, Mauhcaxochitzin, and doña María (all according to Chimalpahin) (central Mexico, seventeenth century)
Codex Chimalpahin: Society and Politics in Mexico Tenochtitlan, Tlatelolco, Culhuacan, and Other Nahuatl Altepetl in Central Mexico; The Nahuatl and Spanish Annals and Accounts Collected and Recorded by don Domingo de San Antón Muñón Chimalpahin Quauhtlehuanitzin, eds. and transl. Arthur J. O. Anderson and Susan Schroeder (Norman: University of Oklahoma Press, 1997), vol. 2, 98–99, 104–105.

Chimalpahin elsewhere says that doña María, daughter of Huehue Mauhcaxochitl, and her husband don Diego Tehuetzquiti, had three children: Tezcatl Popocatzin, don Pedro Mauhcaxochitl, and don Pablo Ixcuinantzin. In this passage a daughter is also mentioned (unnamed) and is said to have gone to Xochimilco. So maybe there were four children from this Tehuetzquiti, after all.
