Frances Karttunen: 

ĪPALNEMOHUANI possessed form, prefixed with third person singular possessive Ī- that one through whom living goes on, giver of life / por quien se vive (C), Dios, por quien se vive (C) There are three attestations (Bf.1r,2r,7r) of longer form ĪPALNEMOHUALŌNI. NEMOHUA is the nonactive form of NEM(I) ‘to live,’ and an alternate, through infrequent, nonactive form is with -HUALŌ. B also has attestations in which the HU is not written and the A, the preceding O, or both are marked long, but this is an –OHUA, not an –OĀ derivation, in spite of the fact that it is almost always spelled ipalnemoani. The possessive prefix is bound with –PAL, not with the whole construction. See –PAL, NEM(I). ĪPALNEMOHUALŌNI See ĪPALNEMOHUANI.

In the Historia Tolteca-Chichimeca, the tlamacazque appear in the shape of town founders, who did penitence and therefore became deserving of founding towns or taking over existing towns. See the attestations from sources in Spanish here in our dictionary. Also, Cohuenan prays to Ipalnemohuani, the Tloque Nahuaque, asking that the people be given "titechtlamacehuia titechmacaz yn mauh y motepeuh" (you grant us, you give us your water, your hill, i.e. your altepetl) after seeing (having a vision of) the Tlachihualtepetl (apparently the pyramid at Cholula). And Quetzalcoatl answers that Cohuenan has earned the benefit of this becoming his altepetl, and the current inhabitants, the Toltecs, will abandon it. (sixteenth century, Quauhtinchan)
