Defunto Don Fernando Arquelles Natural Del Principal de Asturias 1797

I need help from someone please in that you can you tell me what it means when this person that I found in Defuntos in our village of Huejuquilla, Jalisco Mexico in the year 1797.

Says "Don Fernando Arquelles Natural Del Prinicipal De Asturias"

What does it say or mean about Asturias? I have no relation to him but just curious.
