Acamapichtli.

Perhaps the best-known Acamapichtli was a Colhua (grandson of Coxcoxtli) who became the first ruler of Mexico-Tenochtitlan Toltzallan Acatzallan "in the midst of the water, [as] it was called," or the eleventh ruler of the Mexica if counting from when they were in Aztlan.

Another one with this name was the fourth ruler of Culhuacan, sometimes called Huehue Acamapichtli (i.e. the elder). (central Mexico, seventeenth century)

One Acamapichtli was the son of a noblewoman named Atotoztli, who married a Mexica Chichimeca named Izquitecatl tequihua (also called Izquitecatl Iztahuatzin or just Iztahuatzin). When this child was born, the elder Huehue Acamapichtli (said to be the ruler of Culhuacan) and his wife, Illancueitl, came to visit the baby and suggested the baby take the name of the elder. After her husband died, Illancueitl raised the child, the younger Acamapichtli in Coatl Ichan. From there the Mexica took him and he became ruler of the Tenochca. All this information was taken by Chimalpahin from a painting in Culhuacan. (central Mexico, early seventeenth century)
