Alubert
Alubert an eminent Anglo-Saxon missionary, who went over from England and joined Gregory in the superintendence of his school at Utrecht. Persuaded by Gregory, he returned to England to seek episcopal consecration. During the year he spent there, he enjoyed the society of the celebrated Alcuin, then superintending his famous school at York. Having received consecration, he returned and continued to assist Gregory in training missionaries for the Frisians and ordaining them to that office. See Life of St. Liudger; Pertz, Mon.
