Diokno is a Filipino surname that originated from Indang, Cavite and Taal, Batangas area. It was changed to a more Filipino surname from the original Hispanized surname, "Diocno". Ángel Diokno (born c. 1830) is the oldest known patriarch of the immediate family of Gen. Ananías Diokno (son of Ángel). Although the Diokno family members are primarily prevalent in the Philippines,^[1] there are significant numbers of people with this surname in the United States, Saudi Arabia, and other countries.^[2] Through marriages the Diokno clan is also interrelated with multiple historical figures, such as public servants Justice Francis Garchitorena, Corazon Aquino (sixth cousin twice removed of Jose W. Diokno through the Sumulong clan), and Governor-General Félix Berenguer de Marquina y Fitzgerald, who is the namesake of Marikina.
