Tezozomoc (son of Itzcoatl)
Tezozomoctzin was a son of Itzcoatl, the fourth Aztec ruler of Tenochtitlan.
Although Tezozomoctzin never became ruler himself, he was married to Atotoztli II, daughter of Moctezuma I, and three of their sons — Axayacatl, Tizoc, and Ahuitzotl — would become the sixth, seventh and eighth rulers, respectively.
Also, his daughter Chalchiuhnenetzin married Moquihuix, ruler of Tlatelolco altepetl.
