 The Briton Saint Patrick became the evangelist of Ireland during what he called his "peregrinatio" there, while Saint Samson left his home to ultimately become bishop in Brittany.The Irishmen Columba and Columbanus similarly founded highly important religious communities after leaving their homes.Irish-educated English Christians such as Gerald of Mayo, the Two Ewalds, Willehad, Willibrord, Wilfrid, Ceolfrith, and other English all followed these Irish traditions.
