I ran across this defunto of Maria Zaragoza Lopez of Minillas who it says that she passed away in Huejuquilla and was brought to Mezquitic por haber pagado los derechos al cura de Huejuquilla.

Note that it says "se enterro en el Hospital en tierra"
So she was buried in a hospital? At Mezquitic or at Huejuquilla? I wonder where the hospital was back then in the year 1785
This is on page 51 of 280 Defunciones 1771 - 1819 of Mezquitic
