The Durham County Record Office is hosting a talk on the correspondence between the 3rd Marquess of Londonderry and Lord Burghersh between 1814 and 1846.
The 3rd Marquess was a wealthy and influential man, who acquired significant land in County Durham on his marriage to Frances Anne Vane-Tempest.
He was formerly a soldier who served under the Duke of Wellington, and a key player at the Congress of Vienna, which redrew the map of Europe after the Napoleonic Wars.
Lord Burghersh served with Londonderry in the Army and the two were diplomats together in Italy.
The correspondence itself is held at the Durham County Record Office and was purchased in 2017 with generous assistance from the Friends of the National Library and the Friends of Durham County Record Office.
The talk will be delivered by Londonderry expert and former Durham University lecturer Alan Heesom.
Dawn Layland, Durham County Council’s education and outreach archivist, said: “This correspondence is an absolutely fascinating collection of national and international interest that we are lucky to have here in Durham.
“This talk will be a great way to find out more about it.”
The talk will be held on Thursday 15 March from 6.30pm-8pm. Tickets cost £5 and must be booked in advance.
