Boniface of Savoy was a medieval Bishop of Belley in Savoy and Archbishop of Canterbury in England. He was the son of Thomas, Count of Savoy, and owed his initial ecclesiastical posts to his father. Other members of his family were also clergymen, and a brother succeeded his father as count. One niece was married to King Henry III of England and another was married to King Louis IX of France. It was Henry who secured Boniface's election as Archbishop, and throughout his tenure of that office he spent much time on the continent. He clashed with his bishops, with his nephew-by-marriage, and with the papacy, but managed to eliminate the archiepiscopal debt which he had inherited on taking office. During Simon de Montfort's struggle with King Henry, Boniface initially helped Montfort's cause, but later supported the king. After his death in Savoy, his tomb became the object of a cult, and he was eventually beatified in 1839.
Robert Grosseteste, also known as Robert Greathead or Robert of Lincoln, was an English statesman, scholastic philosopher, theologian, scientist and Bishop of Lincoln. He was born of humble parents in Suffolk, but the associations with the village of Stradbroke is a post-medieval tradition. Upon his death, he was almost universally revered as a saint in England, but attempts to procure a formal canonisation failed. A. C. Crombie called him "the real founder of the tradition of scientific thought in medieval Oxford, and in some ways, of the modern English intellectual tradition".
Adam Marsh was an English Franciscan, scholar and theologian. Marsh became, after Robert Grosseteste, "...the most eminent master of England."
