I was researching Arch de la Parr. de Pinos, Zacatecas 1790-1803, listed as Castas....
The last entry for bapts. is 18 apr 1798...then it starts 11 Feb 1793 with marriages. I did not check to see how many years. I am sure some people have not been able to find their ancestors. Hope this helps.
I did not know where to put this information.
