Saint Marcouf was a 6th-century Benedictine abbot and bishop born in the Saxon colony of Bayeux. He served as the abbot at Nantus in the Cotentin and is historically linked to Saint Helier, whom he dispatched to convert the residents of Jersey to the Christian faith. After performing various miracles during his travels, he passed away on May 1, 558, at the Îles Saint-Marcouf. He is traditionally recognized for his connection to the healing of scrofula through the power of his relics.
Life and miracles

During his lifetime, Marcouf visited Jersey, where he was credited with performing miracles. His religious work was closely tied to the efforts of Saint Helier. Following his death, his remains were moved to the abbey of Corbény in Champagne. There, his relics became significant participants in the coronation ceremonies of French kings at Reims.
Legacy and veneration

The saint is famously associated with the royal touch, a tradition where monarchs attempted to cure scrofula by laying hands on the afflicted. This practice was believed to derive from the efficacy of his relics. Today, he is commemorated on May 1, and a dedicated chapel featuring stained glass depictions of his life exists within the Cathédrale Notre-Dame de Coutances.
