Estate administration records relating to the pre-1806 Dderw, Palleg and Tredegar estates in Breconshire, and the successor post-1806 Tredegar Breconshire estate.

The papers comprise records that cannot be allocated to one of the specific constituent estates of the Tredegar estate. Papers relating solely to one of the constituent estates will be found with the records of that estate. Many of the papers listed here relate to (parts of) two or more of the pre-1806 Dderw, Friars, Palleg, Ruperra and Tredegar estates, or to (parts of) two or more of the post-1806 county-based estates of Breconshire, Glamorgan and Monmouthshire. -- John Morgan (1672-1719) of Tredegar inherited the Ruperra estates of John Morgan ('the merchant', dsp. 1715). Both the Tredegar and Ruperra estates included properties in both Monmouthshire and Glamorgan. Estate administration between 1715 and 1806 appears to have been on an ad-hoc basis, the subdivision of the Tredegar, Ruperra and Friars estates into rent 'collections' respecting neither the boundaries of the estates nor the county boundaries. These arrangements generated many individual records that related simultaneously to several estates; these records have been gathered here for convenience. -- Some records, such as those relating to woodlands, deal with an agricultural function across several estates, both before and after 1806. Other records, such as notices of assignments of leases, relate to the urban elements of the post-1806 Monmouthshire and Glamorgan estates. Other records relate to the latter days of the Tredegar estate, dealing simultaneously with the rumps of the various estates. In the case of yet further records, it has not been possible to assign them to their approprate estate. In each of these cases, these records have been gathered here for conveniece.
