Rodriguez-Aramburu & Palafox (1740s Nochistlan)

Hi everyone. I am stuck with these ancestors and wondering if any members have the same individuals listed in their databases. I suspect the Rodriguez's are Rodriguez de Frias, but have no docs to confirm.

MALE TWINS, baptized on 25 Sep 1747, in Nochistlan.
[Parents were ANTONIO RODRIGUEZ & MANUELA ARAMBURU]:
Nicolas Antonio Rodriguez
Nicolas Geronimo Rodriguez

Nicolas Antonio Rodriguez married Candida Eucebia Palafox in Nochistlan on 28 Jan 1761.

Can anyone confirm these were "de Frias'?
Does anyone know who the parents of Candida Palafox were?

I admit, I haven't seen the record yet, as I do not have access to Nochistlan microfilms.

Thanks!
