Vignal is a patois corruption of the Latin Guingualeus, itself a translation of the French Guénolé or Guignole, from the Anglo-Saxon Winwaloe / Winwallus / Winwalloc. There are some fifty variants of his name, which survives in the dedication of some churches in Brittany, Cornwall and Monmouthshire.
St Vignal was born about the year 460, possibly in Plouguin, to Fracan, a prince of Dumnonia [Brittany] and his wife Gwen Teirbron [“Gwen the Triple-Breasted”]. He became the first Abbot founder of the Abbey of Landévennec, just south of Brest, and died there on 3 March 532.
He is supposed to have assisted St Sampson and St Magloire in evangelising the Bailiwick of Guernsey, which includes Alderney, in the 6th century. Some relics were preserved at Montreuil-sur-Mer and in St Peter’s, Ghent, and until the 19th century his tomb was visible in the church at Landévennec.
