Diana Noel, 2nd Baroness Barham (18 September 1762 – 12 April 1823) was a peer, philanthropist and an abolitionist who established schools and churches on the Gower Peninsula.

[2][3] They were Calvinist Methodists, whose friends included religious writer and philanthropist Hannah More, cleric George Whitefield, and politician and abolitionist William Wilberforce.

[5] They had eighteen children,[1] one of whom, Baptist Wriothesley Noel, stated that his parents' home "combined whig politics, evangelical devotion, aristocratic unconventionality, and strong-mindedness in a potent blend".

[6] Gerard's estates, worth £20,800 a year and consisting of 15,000 acres, were put into trust due to the poor state of financial management by 1816.

[1] Her correspondence is archived with that of the Noel family at the Record Office of Leicestershire, Leicester and Rutland[7] and photographs related to her life are held at the Chipping Campden History Society.
