Pedro Calungsod
Pedro Calungsod (Spanish: Pedro Calúñgsod or archaically Pedro Calonsor; July 21, 1654 – April 2, 1672), also known as Peter Calungsod and Pedro Calonsor, was a Catholic Filipino-Visayan migrant, sacristan and missionary catechist who, along with the Spanish Jesuit missionary Diego Luis de San Vitores, proselytized and converted the indigenous people of Guam, in some cases without consent, which led to both missionaries being martyred in 1672. While in Guam, Calungsod preached Christianity to the Chamorros through catechesis, while baptizing infants, children, and adults through colonization.
