Walter de Coventre [SEP] Introduction
Walter de Coventre (died 1371 or 1372) was a 14th-century Scottish ecclesiastic. There is no direct evidence of his birthdate, his family, or his family's origin, although he may have come from the region around Abernethy (in modern-day Perth and Kinross), where a family with the name de Coventre is known to have lived. Walter appeared in the records for the first time in the 1330s, as a student at the University of Paris. From there he went on to the University of Orléans, initially as a student before becoming a lecturer there. He studied the arts, civil law and canon law, and was awarded many university degrees, including two doctorates.
