ALAMINOS began as a barrio of San Pablo City which was then only a town of the province of Batangas. It’s initial name was TRENCHERA denoting the presence of long and deep ravines. The early inhabitants of Trenchera were believed to be INSURECTOS and possibly fugitives who took advantage of the numerous trenches for hiding as well as for defense against Spanish authority.
Sometime in 1873 when a certain DON ANDRES PEÑALOZA was the gobernadorcillo (equivalent of mayor) of the town of San Pablo, Trenchera was formally separated and became pueblo or town but remained part of the province of Batangas.
DON CIRILO BAYLON, a wealthy resident of Trenchera and with a good command of Spanish language invited Captain-General JUAN DE ALAMINOS NIVERA, the chief executive of the province of Batangas whose capital seat was Lipa. The Captain-General accepted the invitation and came in colourful carriage drawn by two horses. With DON CIRILO BAYLON leading, he was warmly received by residents of Trenchera. DONA GREGORIA BAYLON, the younger sister of Don CiriloBaylon presented bouquet of fresh flowers to the Captain-General.
During the program in honor of the Captain-General and his party, Don CiriloBaylon presented the petition of the resident asking that TRENCHERA be made into a duly organized and recognized town. The petition was read in public and the Captain-General gave assurance to consider their wish favourably. In less than two months the official paper proclaimaning TRENCHERA as a new pueblo or town arrived from Lipa, then the seat of power of the province of Batangas.
At the same time, DON CIRILO BAYLON was appointed the first gobernadorcillo or town mayor in concurrent capacity as Captain de los Constables de Pueblo or the equivalent of the local police chief. In appreciation of CAPTAIN-GENERAL JUAN DE ALAMINOSNIVERA,the new pueblo was named ALAMINOS in 1873 and remained part of the province of Batangas until 1903.
