Huizares de Valparaíso

I have reached a dead end in my research on the Huizares of Tototiche which ends with a couple who lived in Valparaíso in the late 1700s. Does anyone have any information on this family or where I could find further information on families that lived in Valparaíso during this time? Are these records in Huejuquilla, Jerez, nowhere?
