George Frederick Nugent, 7th Earl of Westmeath PC (18 November 1760 – 30 December 1814), styled Lord Delvin until 1792, was an Irish peer.

He gained notoriety in his own lifetime, due to his unhappy first marriage to Maryanne Jeffries, which ended in divorce, following a much-publicised legal action by the husband for criminal conversation.

There is no reason to doubt the claim made by Lord Westmeath's counsel at the trial that he hesitated for a long time before deciding to end the marriage: divorce then invariably caused scandal, and the process was slow and expensive, requiring a private act of Parliament.

Also, a cuckolded husband was traditionally a figure of fun, and his wife's infidelity did expose Westmeath to a good deal of ridicule, both among his neighbours and in the press.

Even while exercising his official duties as a Colonel of Militia, when he accidentally entered the bedroom of a married woman, he was told pointedly that she (unlike some) was a virtuous wife.

[3] Although he was a rich man, financial motives may partly explain his decision to sue for criminal conversation, as he sought the (then) very large sum of £20,000 (on the other hand Cavendish-Bradshaw was notoriously short of money, and probably never paid the damages).

On that basis he attacked the character of both husband and wife, describing Lady Westmeath as an experienced woman of the world who had seduced a much younger man.

[7] Whether he actually recovered the damages is unclear, as Bradshaw was a poor man all his life, who spent years lobbying each government in turn for any lucrative office which might be vacant, and was invariably refused.
