Regino Relova y Díaz (August 2, 1874 – June 18, 1961) was a lieutenant-colonel of the Katipunan who fought during the Philippine Revolution in Los Baños, Bay, Calauan, and his hometown Pila, Laguna during the Philippine-American War (also known as the Philippine Insurrection).
Relova was born in Pila, Laguna to parents Don Feliciano Díaz Relova and Doña Concepción Díaz. Feliciano, God-fearing and industrious, was a three-term Capitan Municipal of Pila in 1875-1876, 1885-1888 and 1895-1898.
Feliciano and Concepción had nine children, namely eldest Ruperto, Paz, Socorro (who died a young maiden), Regino, Iñigo, Santiago (great grandfather of Lia Relova Price), Arcadio (great grandfather of Dominic Ochoa and Maverick Relova), Federico and José (whose son, Lorenzo Relova, became Associate Justice of the Supreme Court).
Feliciano’s parents (Regino Relova’s grandparents) were Don Regino Reloba de San Antonio and Doña Oliva Díaz and sisters Salomé (who married a Ruíz) and Eduvigis (who died a young maiden). Don Regino Reloba de San Antonio, who changed his surname to Relova after a decree by Spanish Governor General Narciso Clavería y Zaldúa on November 21, 1849, was Capitán Municipal of Pila in 1855-1856. Don Regino Reloba de San Antonio’s parents (Regino Relova’s great grandparents) were Don Alejandro de San Antonio and Doña María Oca. Alejandro is considered to be the first Relova in Pila as he could have moved from Pasig to the present site owned by Don Felizardo de Rivera at the time of its complete transfer from Pagalangan on May 20, 1804.
Regino Relova was already set out for life as a haciendero with the vast rice and coconut landholdings that formed the massive wealth of the Relova clan in Laguna at that time. But he longed for an exciting life as, according to local town historian Dr. Benjamin Ruiz, he inherited the adventuresome spirit of Alejandro that could have led him to a life as a Katipunero. As the revolution broke out in August 1896, Laguna was one of the first eight provinces to rise against the Spaniards’ oppressive rule. Although Laguna had that distinction, the municipal governments and the principalia in the province were generally reluctant to fully support the revolution.
Feliciano, who felt the Filipinos were not yet ready, tried to prevent son Regino Diaz Relova from actively taking part in it. The Feliciano brought his son to relative Kapitan Penalosa in Lucban and were advised, after week’s stay, to seek an audience with Marquéz de Solier, the Gobernador Provincial in Santa Cruz, Laguna so as not be placed under suspicion of being Katipuneros. The Relovas and other Pila officials, went to Santa Cruz on November 23, 1896 but were immediately arrested and jailed for nine days. They were incarcerated as a certain Quisumbing from Los Baños tagged them as insurrectos who fed the revolutionaries and added that bullets were being made in the house of Juan Bartolomé.
