Is-is-is-fonds AGD - Glamorgan rent ledgers

The Glamorgan ledgers begin with the reorganisation of the Tredegar estates in 1846. Almost from the start the ledgers are created in groups, with a single ledger for 1846-1852, two volumes 1852-1862, and a block of four volumes started in 1862. A number of volumes were then started, from 1869, apparently as needed, until a block of five volumes were started 1892-1894. The creation of a separate series of Cardiff audit books in 1877 seems to go un-noticed among the ledgers; although ledgers may have become either predominently rural or predominently urban, the title 'Cardiff ground rents' first appears on a spine in 1893, and even then other 1893 volumes of rents in Splott and Roath continue to be intitled 'Glamorgan estates'.
