Diokno

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.

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.

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.[3][4] Notable members of the main branch of the Ananías Diokno family include:
