By some historiographic traditions Xolotl founded Tenayuca ca. 1224. Xolotl was succeeded by Nopaltzin who consolidated the Chichimec Kingdom. His daughter was Cuetlaxochitzin, Queen of Azcapotzalco, wife of the king Acolnahuacatl and mother of famous Tezozomoc.
^In the García Granados Codex the Azcapotzalco blood line is outlined in the following order: Maxtlacozcatl (Matlacohuatl), Chiconquiauitl, Tezcapoctli, Tehuehuactzin, Micacalcatl, Xiuhtlatonac, Acolnahuacatl and Tezozomoc; the Tlatelolco annals provide another list in which the first three and the two last names appear but misses the other three; the advantage of the second list is that these are the proposed dates in the article.
