Saw this page in the defunto archives of the year 1780 and may give clue as to where the cemetary was at that time with this comment written:

"Razon de las personas que se mueren y entierren en el pueblo de la soledad filia de esta Parroquia"

La Soledad is a ranch I think. Could be the place where it is at.
