Agents of Marquess of Anglesey, mining employees and consultants.

Peckover, Burrill and Owen of High Street, Bangor acted as land agents for the Marquess of Anglesey in north Wales. This collection relates mainly to copper mining in the parish of Amlwch, Anglesey, in particular at the Parys Mountain and Mona mines owned by the Marquess.

Henry Bayly (1744-1812), 9th Baron Paget and heir of Sir Nicholas Bayly formed the Mona Mine Company in 1785 together with Thomas Williams of Llanidan (1737-1802), to work the rich deposits of copper discovered on the eastern side of Parys Mountain, near Amlwch in 1762. He also owned half of the Parys Mine Company. Henry was succeeded by his eldest son, Henry William Paget (1768-1854) who was created first Marquess of Anglesey in 1814 as a reward for his military achievements at Waterloo, where he lost a leg.
