Plegmund a noted prelate of the early English Church, flourished near the close of the 9th century. He was the friend and fellow-student of Alfred, and was in 890 elevated to the archbishopric of Canterbury. We know next to nothing about his personal history, but we are aware of the influence he exerted on ecclesiastical affairs through Alfred.
