de Ejército (May 2, 1906[2] – January 13, 2009), also known as Doña Mary, was the mother of Joseph Ejercito Estrada, the thirteenth president of the Philippines.

[citation needed] In 1998, Ejercito received the "Ulirang Ina" ('Exemplary Mother') award from the Philippines’ Elderly Persons Foundation.

[4] During President Estrada's impeachment trial, news of the political crisis was deliberately withheld from her, but after receiving information of the proceedings she advised her son thusly: "It's more than high time you change.

"[5] Ejercito's health began to decline during her son's six-year incarceration; the ousted President would occasionally be granted furloughs to visit his ailing mother.

[7] On September 12, 2007, Estrada was convicted by the Sandiganbayan (a special appellate collegial court) of plunder charges and sentenced to reclusión perpetua.
