request for assistance

[Santo, Joseph A.]

I am writing from the School of Music of The Catholic University of
America, Washington, D.C. I am a composer, and I am attempting to
confirm the accuracy of a short text (for musical purposes), which I
believe to be in nahuatl. I found the text on an internet site, and it
is supposed to be a translation of the "Ave, María." Since I am
interested particularly in the second half of the prayer, I am copying
only that part here:

...Santa Mariaè, Dios Inantzinè, ma topan ximotlâtolti in
titlâtlacoanime in axcan, ihuan inîquac yê tomiquiztempan. Ma yuh
mochihua.
This is supposed to translate: "Santa María, Madre de Dios, ruega por
nosotros pecadores ahora y en la hora de nuestra muerte. Amén."
I am trying to ascertain (a) whether it is indeed in correct nahuatl;
(b) the accuracy of the nahuatl translation; (c) how or if the
circumflex on some of the vowels changes the pronunciation of that vowel
or accentuation of the word, e.g. â, î, ê; and (d) what is the effect on
pronunciation/stress of the final grave e (Mariaè, Inantzinè), which
looks like a vocative. I understand that stress is on the second to the
last syllable in nahuatl, though I am not aware if there are any
exceptions.

I would be most grateful for any assistance anyone might be able to
offer regarding this short text.

Sincerely,
