Drogheda, County Louth
|Died||28 March 1824
Wilmot was born in Drogheda, County Louth, to Edward and Martha Wilmot (née Moore). She was the eldest daughter of six daughters and three sons. Her father was the port surveyor in Drogheda, but has previously served as army captain in the 40th Regiment of Foot. He was transferred to a similar post in County Cork in 1775, where Wilmot was raised. The family settled in Glanmire, near the seat of the Earl of Mountcashell in Moore Park.
Wilmot was friendly with Lady Mountcashell, formerly Margaret King, an early and eager pupil of Mary Wollstonecraft. Wilmot was invited to accompany the party of Stephen Moore, 2nd Earl Mount Cashell, and his wife on a grand tour of the continent. Her letters from the time survive, in France from November 1801 to October 1802, and in Italy until July 1803. The Mount Cashells entertained lavishly, especially during the first nine months in Paris, and through them she met Napoleon Bonaparte, and made friends with the Austrian painter Angelica Kauffman. She also met the French diplomat and politician Charles Maurice de Talleyrand-Périgord, and the Irish republican Robert Emmet fleetingly. In Rome she recounts her meeting with the English aristocrat Frederick Augustus Hervey, and her audience with the Pope, Pius VII. Wilmot returned to London from Italy in October 1803, via Germany and Denmark, after England and France resumed hostilities.
Wilmot then went to Russia to bring home her sister Martha, and spent two years there. Martha was in the country as a favourite of Princess Dashkov, one of the key figures of the Russian Enlightenment and a close friend to Catherine the Great. Martha was living at the Princess's estate in Troitskoe (on the Oka River, about 100 km from Moscow. Katherine Wilmot arrived on 4 August 1805, having set out from Cork on 5 June. Wilmot's writings from this time record the Russian aristocracy's opulence and attitudes to the servile classes. The sisters came to know the customs the Russian elite, as well as the festivals and religious rites of the country people. Wilmot left Moscow on 4 July 1807, a combination of passport problems, wars and storms at sea, resulted in delays and in her reaching Yarmouth on 7 September 1807, and returning to Ireland in October 1807.
Wilmot moved to France, Moulins, to live in a warmer, drier climate than Ireland. Her health declined when she moved to Paris, dying there 28 March 1824.
A portrait of Wilmot which was painted in Russia by an unknown artist is known to have been in the possession of Janet Adam, Wilmot's great-great-great-grand-niece, in 1992.
Wilmot had taken Martha's transcript of the memoirs of the Princess Dashkova when she left Russia. These were published by Martha in 1840, as she had burnt the original manuscript before her departure from Russia in 1808.
Wilmot's letters were published a century later, and have been described as a unique portrayal of the Napoleonic period. They describe the social scene, as well as the experience of travelling by coach and ship at that time. The family made transcriptions of the letters; the collection belonging to Martha were donated to the library of the Royal Irish Academy by Elisabeth Lecky (née van Dedem), the widow of historian William Edward Hartpole Lecky. Amongst these Russian letters are a number written by Eleanor Cavanagh, who described the lives of servants. Wilmot's diaries were published in 1920 by Thomas Sadleir, and later by H. Montgomery Hyde and the Marchioness of Londonderry.
