In addition, in order to cover the travel of Felipe as Minister Plenipotentiary and contribute funds to the cause of separatists, said that Marcela had to sell all the jewels and the family's most precious belongings.
In December 1897 the revolutionary general Emilio Aguinaldo, newcomer to Hong Kong after the signing of the Pact of Byak-Na-Bato, commissioned to Marcela Agoncillo the making of the flag of the Philippines following the previous design by the patriotic Junta; According to his own testimony this task took five working days, being aided by his eldest daughter, Lorenza, and a niece of José Rizal, Delfina Herbosa. Apparently, the beauty of the flag was praised by the own Aguinaldo, who waved it on the balcony of the City Council of Cavite on June 12, 1898, in the solemn proclamation of independence.
After the establishment of the American regime (1903) Marcela and her family returned to the Islands, ruined but proud of the work done; Even so, the Chronicles of the time feature that continued helping Manila's poorest people. During the Japanese occupation of the Philippines (1941-1944) Marcela Agoncillo became again a symbol of patriotism and generosity, facing with courage and despite his advanced age, loss of home and property.
