Which "Indio Tribe" are people from Mezquitic or Zacatecas area during Colonial times?

I have a question to ask? When I have been researching our ancestors in the LDS archives for the Mezquitic area of Jalisco, Mexico. And ran across people stated as "indio" which indio tribe?

Huichole? I don't know since the Huicholes were suppose to be originally from San Luis Potosi who migrated more into the remote areas of Jalisco and Zacatecas after the Spanish arrived.

Chichimeca's were the inhabitants when the Spanish arrived.

So how can we tell which Indio Tribe are the people from at the time when they were recorded in the Catholic Records?
