Pedro Calungsod, Filipino catechist and sacristan; later canonized (died 1672)

Pedro Calungsod, 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 forcefully converted the indigenous people of Guam, in many cases without consent, which led to them being martyred in 1672.
