Benito Calayag San Diego (Abt 1870 – 1944) of Obando, Bulacan, Philippines was the son of Teodoro Roxas San Diego and Candida Lopez Calayag.
Benito was baptized on 24 March 1872 in San Pascual Baylon Parish, Obando, Bulacan — he was 4 days old. He carried the name “Benito Cuerva San Diego” in church documents and, like his father, did not use his mother’s maiden name. This writer hypothesizes that generations before, a woman from the prominent Cuerva Clan married a San Diego, who was socially undistinguished. The practice may have been carried on for generations, until the social benefit ceased to exist.
According to oral histories, Benito had 4 brothers — two migrated to the Visayas, two stayed in Obando, while he migrated to the city of Manila. In the 1910s, he worked for the US Army Quartermaster Corps, located at the Port Area, Tondo, Manila City.
