The indios amigos were not listed on the 1540 muster but many were present. They also rarely appear as individuals in the documentary record. Luckily, several served as witnesses after the Expedition returned to New Spain. Juan Tlecanen testified that he went on the expedition and that he was a principal in Mexico City, which suggests that he commanded at least some of the indios amigos.

Other info: Gibson, Aztecs [p.370: Juan Tecçane is presumably another spelling of the name of Juan Tlecanen, whose testimony immediately precedes that of Juan Cacçol. The community of San Juan mentioned here is San Juan Moyotlan, the southwestern quadrant of the Indian altepetl of Tenochtitlan, which in its entirety encircled the Spanish settlement, México. The remaining three component calpolli of early colonial Tenochtitlan were Santa María Cuepopan in the northwest (mentioned here as the home of Martín Xalacate); San Sebastián Atzacualco, in the northeast; and San Pablo Zoquipan, in the southeast]
