Hyacinthe-Gabrielle Roland

Hyacinthe-Gabrielle Wellesley, Countess of Mornington (née Roland; 7 November 1816), was a French actress who became the mistress, and later the wife, of Richard Wellesley, 1st Marquess Wellesley. As an actress, she was billed as Gabrielle Fagan.
Through her daughter Anne, Wellesley is the great-great-great grandmother to Queen Elizabeth II.
Parentage.
She was born in Paris between 1760 and 1771 to Pierre Roland and Hyacinthe-Gabrielle Varis. There were rumors Roland's biological father was Christopher Alexander Fagan, and she was later adopted by Pierre Roland.
Her birth year is also unproven. The University of Southampton, which houses the Wellesley family papers, estimates her birth year to be 1760. "The Complete Peerage" and "Burke's Peerage" estimate her birth year to be between 1766 and 1771 in editions published since her death.
Marriage.
Richard Wellesley, the son of Garret Wesley, 1st Earl of Mornington, met Roland at the Palais Royal where she was an actress. She spoke no English at the time, however they lived together for some years without marrying. In 1781, Richard Wellesley succeeded as 2nd Earl of Mornington. He and roland married on 29 November 1794 at St George's, Hanover Square, London. Prior to their marriage, they had three sons and two daughters who were then legitimated:
Upon her marriage, Roland became the Countess of Mornington, but remained a social outcast. In 1799, her husband was created the 1st Marquess Wellesley, making Roland a courtesy marchioness. However, this elevation did not change her social standing. Even the famously casual Elizabeth Lamb, Viscountess Melbourne refused to call on Roland, and scolded her daughter-in-law, Lady Caroline Lamb, severely for doing so.
Separation and death.
In the course of their marriage, Wellesley had at least two illegitimate sons by another mistress, Elizabeth Johnston. In 1797, when Wellesley was obliged to travel to India in his capacity as Governor General, Roland did not accompany him, although he tried repeatedly to persuade her. There is some evidence that she was already seeking a legal settlement for divorce prior to Wellesley's departure.
By 1801, Roland's letters detailed accusations of her husband's infidelity with another Frenchwoman, Madame de Cocrement, and of neglect of his family. Upon Wellesley's return to Britain, he purchased Apsley House as a family home, but the couple were again estranged and Wellesley took another mistress. They formally separated in 1810, and Roland left the Apsley House. She lived for a time in Grosvenor Square and then in Great Cumberland Place.
On 7 November 1816 , Roland died at Teddesley Hall, Staffordshire, a house belonging Edward Littleton, MP. Husband to her daughter Hyacinthe Marie.
