The Glamorgan estate began to gather rural cottage and farm rents and urban ground rents accounts into separate ledgers almost from the begining of the estate in 1846. However the first ledgers described on their spines as Cardiff ledgers are dated 1893, and these form the first volumes in this series. Their predecessor volumes will be found among the Glamorgan estate ledgers (AGD 1), as will contemporaneous ledgers of ground rents in Splott and Roath while they continue to be described as Glamorgan ground rents. -- The rent ledgers were reorganised in 1925, with two series of loose-leaf volumes intitled Cardiff Urban A to K (AGD 2/27-37), and Glamorgan Urban W to X (AGD 1/27-28) gathering together groups of streets in alphabetical order, A (A-Br), B (Bu-Cl), C (Co-D) etc. Many of the accounts end with the freehold being conveyed, mostly in the period 1955-60, and often to the tenant, but also, for example, to the Cardiff & Co. Superanuation & Benefit Society, Cardiff Corporation, Cossam Investment Co. Ltd, Glam. Estates Ltd, Gwalia Land & Prop. Dev. Ltd, and Valley Properties (Hengoed) Ltd. Notes on the accounts include the deaths of tenants and other changes of tenant, war damage and war damage compensation, and mortgagors. AGD 2/38-40 contain of folios taken out of AGD 2/27-37 and AGD 1/27-28. These folios appear to apply to properties, the freeholds of which were conveyed during the life of the volumes. Most, if not all, of the freeholds were conveyed in the period 1926-52.
