Don Perpetuo Agoncillo and Doña Fidela Marasigan de Agoncillo were a prominent couple from Taal, Batangas in the mid to late 1800s. Both hailed from landed families and had eleven children. Don Perpetuo ran a highly successful shipping business during the latter years of the Spanish rule up to the time of the Japanese Occupation in the Philippines.

Their children were: Hospicio, Maura Agoncillo de Frial, Rosario Agoncillo de Calicdan, Vicente Agoncillo, Artemio Agoncillo, Manuel Agoncillo, Paz Agoncillo de Castillo, Juanito Agoncillo, Matilda Agoncillo and Antonio Agoncillo.

This is an attempt to bring together the descendants of Perpetuo and Fidela through their 10 children, in addition to the existing family tree and website at geni.com.

Perpetuo was a close relation of Felipe Agoncillo, the first Filipino Diplomat and husband of Marcela Agoncillo, who sewed the first Philippine Flag. Marcela gave one of her thimbles to Maura Agoncillo. This was donated by one of her daughters to Imelda Marcos. The thimble now sits on display at the Malacanang Museum.
