Blessed John Shert was an English Catholic priest and martyr, who was executed during the reign of Elizabeth I. He was born at Shert Hall near Macclesfield, Cheshire, and received his degree from Brasenose College, Oxford, in 1566. He worked as a schoolmaster in London, then as servant to Dr Thomas Stapleton in Douai, before entering the seminary in 1576, where he was ordained a subdeacon. He attended the English College in Rome, where he was ordained to the priesthood. He then went to Rheims. On August 27, 1579, he left Rheims for England, where, along with Thomas Ford and Robert Johnson, he was executed on May 28, 1582. All three were beatified in 1889.
