John Finglow was a 16th-century English priest who served the Catholic Church during a period of intense religious tension. Born in Barmby, East Yorkshire, he studied at Caius College, Cambridge, before traveling to the English College in Reims to pursue his vocation. Following his ordination in 1581, he returned to England to conduct missionary work. His activities in northern England eventually led to his arrest by authorities, resulting in his execution in 1586.
