#WikiPinoy of the Day: Delfina Herbosa was a Filipina revolutionary and niece of patriot and polymath Jose Rizal. She joined the women's chapter of the Katipunan where she met her husband Jose Salvador Natividad. Both became involved in various battles against the Spaniards. Following the truce of the Pact of Biak-na-Bato, Delfina and Jose joined the resulting self-exile of revolutionary leaders in Hong Kong. Delfina helped Marcella Agoncillo sew the Philippine flag that will be unfurled on June 12, 1898 in Kawit, Cavite.
