I am curious about what was Real De Asientos for in Aguascalientes and if there were those places in other towns of Mexico?
Also what is a Mercader?

Then I went to "Tipo Documental" and a long list came up and was looking at some. I looked at "compraventa esclavos" and it had a list of people that bought slaves, gives names, and the slaves they bought.
I was browsing through the names and saw that in 1724, "Melchor De Richarte Mercader, Fernando De La Campa y Coz Coronel De La Infantria Espanola" :
