1648 Census of Valpariaso and Rancho Carboneras, Zacatecas, Mexico

Hi everyone,

I want to ask anyone what distance is a "legua" that was used in Zacatecas year 1648?

Here is a census of Valparaiso and Rancho Carboneras year 1648. That rancho belonged to my ancestor Joan Angon. But on the census it shows him listed first at Valparaiso while his son Esteban Angon is listed in Rancho Carboneras.

Rancho Carboneras was located 5 leguas from Fresnillo and Valparaiso 20 leguas from Fresnillo. They were under jurisdiccion of Fresnillo.

There was a Cofradia at the rancho of Joan Angon and presumably at Rancho Carboneras. There is a whole archive that was logged like a diary from 1632 - 1700 in regards to that ranch and it is called "Cofradias 1632 - 1700."

It is under Huejuquilla, Jalisco.

Joan Angon was father of Esteban Angon. I believe Maria Angon was daughter of Esteban Angon. Maria Candelaria Angon (1655 - 1735) was married to my direct ancestor Antonio Madera (1660 - 1709) on my family tree:
