Gilbert Welton was an eminent ecclesiastical administrator who won papal favour when visiting the Curia at Avignon. He recruited qualified staff before settling in the impoverished, war-torn diocese of Carlisle, which had not been accustomed to a resident bishop or to a high standard of episcopal government. His professionalism is reflected in the professional quality of his register. Among its contents are a dozen records of matrimonial causes (one Carlisle woman was divorced twice in six weeks), of further social interest are the 59 wills of laymen and beneficed clergy, many of them victims of the second visitation of the Black Death in 1362. This volume offers a calendar of the whole manuscript, with an appendix of full Latin texts of entries of special interest.
