Translation help--little pamphlet

[Quis ut Deus]

OK, I am going to try to translate a small pamphlet. It is written in Spanish, so I will post the Spanish first, then the English, then my attempt at the Latin.

I await any correction and suggestions!

OK, here is the title page:

SP:"Oracion que rezaba la beatita de Patzcuaro"

EN:"The Prayer that the Little Blessed Lady of Patzcuaro Prayed"

LA: "Oratio quae beata de Patzcuaro orabat."

My questions here are:

Is my use of the relative pronoun correct and how do you form the dimunitive in Latin ("beatita" is diminuitive in Spanish).

Gratias vobis ago et Valete!

[Quis ut Deus]

No wait!

It should be "Oratio QUAM beata de Patzcuaro orabat."

[adrianus]

Salve Quis ut Deus

Yes/Rectè dicis, "quam".

beatita = beatula è Patzcuaro—substantive from the adjective, the diminutive form of 'beatus -a-um' /substantivum à 'beatulus -a -um' adjectivo, quod adjectivum deminutivum à 'beatus -a -um' derivatum est.

[Quis ut Deus]

Salve Adrianus!

So, I need to use "ex" instead of "de" for describing where people originate from.

Vale!

No. Confusing maybe, but it's yes to all of the prepositions "de" and "e/ex" and "a/ab" for place origins, I believe.
Non est. Res turbata forsit sed, ut credo, omnis praepositionum sequentium ante locum originis apta est: "de" vel "e/ex" vel "a/ab".
