Maria Seymour-Conway, Marchioness of Hertford
Maria Emilia Seymour-Conway, Marchioness of Hertford (born Maria Emilia Fagnani; 24 August 1771 – 2 March 1856), nicknamed Mie-Mie, was a British noblewoman of Italian descent.
Illegitimate daughter of Costanza Brusati, by marriage Marchesa Fagnani, her true paternity remained surrounded in controversy.
During their long trips in northern Europe, Marchese Giacomo II Fagnani and his wife Costanza Brusati met in England Henry Herbert, 10th Earl of Pembroke, an English aristocrat well-known for his amorous intrigues with Italian women. The three began to travel together, and the Earl of Pembroke began a secret affair with the Marchesa Fagnani.
In the winter of 1769 Costanza Brusati (who left her husband) and the Earl of Pembroke arrived to London, where he introduced her to a friend, William Douglas, Earl of March, who was among the best-known bon vivants of the reign of King George III and was known as "Old Q" because that letter was painted on the door of his carriage. Soon after, the Earl of March and Costanza Brusati also began a love affair.
On 25 August 1771 at the White's club of St James's, the Earl of March sent a letter to his friend George Selwyn (a prominent politician) that the previous night the Marchesa Fagnani gave birth a daughter named Maria Emilia, and that he was the father. Selwyn took custody of the newborn and brought her up as her own daughter, arising rumors that in fact he could be the real father.
Shortly after, Costanza Brusati returned with her husband, who recognized Maria Emilia as his own; however, the child remained in England. They had two children: Federico (born in 1775) and Antonia Barbara Giulia Faustina Angiola Lucia (nicknamed Antonietta; born in 1778), later by marriage Marchesa Arese.
In 1777 Costanza Brusati, in order to please her parents-in-law Federico II Fagnani and Rosa Clerici, asked the intervention of the Earl of March for the return of her daughter to Italy. However, he refused to intercede before Selwyn, who nevertheless was forced to hand Mie-Mie in Paris, so that the mother could bring her back to Milan.
Only in 1786, after the death of Federico II Fagnani, George Selwyn arrived in Italy to convince Costanza Brusati to give him back Mie-Mie. At the end, the Marches accepted, and allowed George Selwyn to appoint her daughter as heiress of his estate; in addition, the Earl of March (since 1778 also Duke of Queensberry) left much of his fortune to Maria Emilia when he died in 1810.

- Captain Richard Seymour-Conway, 4th Marquess of Hertford (1800–1870).
- Lord Henry Seymour-Conway (1805–1859).
It's said that when King George III was insane, he announced that he was going to take Lady Yarmouth as his mistress.
Despite her wealth, the Seymour-Conway family never accepted Maria Emilia due to her illegitimate origin, and at the end this affected her marriage: after the birth of her last child, she moved to Paris, where she remained for the rest of her life. Because she never divorced her husband, when her father-in-law died in 1822 she became in Marchioness of Hertford.
The intricate custody battle for Mie-Mie and especially the controversial existence that she lived for many years in London and Paris had considerable echo in the aristocratic and upper-class society of her time. William Makepeace Thackery parodied her husband as the Marquess of Steyne in his masterpiece, Vanity Fair.
