UKBMD and GENUKI describe it as "an ancient parish church housed in Chester Cathedral, serving part of the city of Chester. Closed in 1882 and succeeded by Chester: St. Thomas of Canterbury." The FamilySearch Wiki says the church was in Queen Street and after it was closed the congregation was served by the church of St.Thomas of Canterbury, Parkgate Street.
