Charlotte d'Argenteau, comtesse d'Esneux
The only surviving child of Louis Conrad d'Argenteau, Count d'Esneux, and Marie Ghisberte de Locquenghien, Charlotte d'Argenteau met Lord Ailesbury when she was 21 and living in Brussels, Belgium, with her widowed mother. Brussels gossip had it that despite her good qualities she would never marry, due to a small dowry and her mother's appalling temper. Within a short time of meeting her Ailesbury fell in love, and it seems his feelings were returned; friends however warned that Charlotte's mother would probably make difficulties. The Countess did so, and perhaps not unreasonably: Ailesbury was more than 20 years older than Charlotte; more importantly he had fled England to avoid being condemned as a traitor and though the British Crown had not seized his estates he was only able to draw part of the revenue. Eventually he overcame his future mother-in-law's objections, although it is clear from his memoirs that he disliked her intensely.
The marriage was very happy. Charlotte was described as "a noble and virtuous lady, born to make anyone happy". In his memoirs her husband, who rarely spoke of his first wife Elizabeth, wrote of his second wife that "there was scarce her equal in goodness and sweetness and generous to the last degree"; although he cannot resist the gibe that she was "the reverse of her mother". Charlotte's stepchildren, Charles and Elizabeth Bruce, became deeply attached to her and she had one daughter of her own: Lady Marie Thérèse Charlotte Bruce, born in 1704. Ailesbury settled in Brussels so happily that when in time the English government made it clear that he could return home, he no longer had any wish to.
After ten years of marriage, Charlotte died of a fever in July 1710, aged 31, and was buried in the Church of the Brigittines, Brussels. Ailesbury was deeply grieved, and though he outlived her by 30 years never remarried. Their daughter Marie Thérèse became the wife of Maximilian, Prince of Hornes, and among Charlotte's great-grandchildren was Princess Louise of Stolberg-Gedern (the Jacobite consort from 1772–88).
