Diokno

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, there are significant numbers of people with this surname in the United States, Saudi Arabia, and other countries. 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.

Family of Ananías Diokno
Because of the Irish ancestry of Berenguer de Marquina coming from the noble Fitzgerald clan, he descends from some Norman French or English, and European nobles such as Saint Begga of Belgium by forty degrees. St. Begga is the great-great grandmother of King Charlemagne and daughter-in-law to St. Arnulf of Metz, France. The great-great grandson of Berenguer de Marquina is Ananías Diokno, who also descends from William Boleyn, who is the grandfather of Elizabeth I of England. Berenguer de Marquina had an illegitimate Chinese mestiza daughter from Cagsawa, Albay who married a Spanish-Mexican public servant surnamed Sauza, whose daughter settled in Taal, Batangas, marrying a member of the Tagalog Noblejas clan. Their daughter María Andrea Noblejas y Sauza (born c. 1834), who descended from Berenguer de Marquina, became part of the Diokno family by marrying Ángel Diokno (born c. 1830). Because of the Fitzgerald clan, the line at least starting Ananías Diokno y Noblejas can trace its roots to nobles, public servants, soldiers, and saints from the first century A.D.
