The family patriarch Sixto Pe married Joaquina Gutierrez a native mestiza, half Igorot – half Spanish from the highlands of the Philippine Islands. They changed their last name “Pe” to Dominguez adopted from their godparents by marriage due to limitations of right in owning lands during the Spanish occupancy at the turn of century. The couple started forming their hacienda by investing in gold and copper mining, cattle raising, orchards, vineyards and rice fields acquiring vast lands all the way through the Mt. Province to the higher lands of Ilocos. They had ten children and the descendants went on to build great establishments from trading post, gas station, trucking, commercial buildings, hotels, subdivisions, drug store, restaurants, residential apartments and bus liner all existed till today. The first son Pedro Dominguez was the first politician in the family, holding the title President of Mt. Province equivalent to a Governor in present political lingo. Branches of the family are found in most part of the country and the United States as well as in Europe.
