Southern Luzon
Below are links to transcribed historical data documents for provinces, cities, municipalities and barrios found in southern part of the island of Luzon. The reader/researcher will please note that the geo-political/administrative units that existed in 1953, when these historical data were submitted upon the order of then-President Elpidio Quirino, were different from what they are in the present day.
There would have been certain geopolitical/administrative units that had merged with others or were subdivided, so that the historical data of certain geopolitical/administrative units may be found included in the documents of adjoining units.
