Social Reformer. She received a place in French history for her part played in the French Enlightenment period. Born Alexandrine Louise Sophie de Caritat de Condorcet, who was simply called “Eliza,” took her place in French history by supporting her parents and husband's beliefs that all humans should be treated equal, including the abolishing of slavery and the advancement of women. She was the only daughter of noted French mathematician and philosopher, Marquis de Condorcet, and his wife Sophie Grouchy, the daughter of a French aristocrat. At the Hôtel des Monnaies in Paris, her mother entertained in her salon many of the world's most-known politicians, British noblemen, and writers, including women writers supporting women's rights. As a writer, her mother was highly educated, spoke fluent English, Italian, as well as French, and translated the writings in French of American patriot, Thomas Paine along with other political authors. Her mother was also a pastel portrait artist. As a child, Eliza Condorcet O'Connor had the opportunity to learn from the world's masters. She was seven when her father died imprison while fleeing French Revolutionary authorities. Some historians claim, “she was conceived on the night of the fall of Bastille.” Her maternal uncle was , Emmauel de Grouchy, the commander of Napolean's forces that aborted the invasion of Ireland. When she was only 17-years-old, she married the 44-year-old exiled Irish patriot, Arthur O'Connor, on July 4, 1807 . There was also a vast age difference between her parents' ages. After her mother's death, she and her husband continued editing her father's volumes of manuscript with publishing dating 1847 to 1849. She had started collecting her father's essays for more than twenty years before in hope that she would some day have them published. This manuscript is still being quoted in the twenty-first century on the subject of human rights. She and her husband had five children: three sons and two daughters. All of her children are assumed to have died before her husband's 1852 death, which gave both unbearable grief. Only one son, Daniel, married giving her two grandsons, Arthur and Fernand O'Connor. Through her grandson Arthur's daughter, she is the direct ancestor of the French poet, Patrice de la Tour du Pin. Many of the O'Connor descendants have become accomplished citizens with some serving in the French military and being highly decorated. The family still lives at Chateau du Bignon with its vast garden, and at one time, poet Patrice de la Tour du Pin owned the castle. She received a widow's military pension upon her husband's death. Originally buried on the grounds of Chateau Bigon, she and other members of her family were moved some years later to the family Greek-style crypt in the village cemetery. One of her father's last publications was, “Opinion of an Outlaw and Advice to My Daughter.” Eliza O'Connor reveals a great deal about herself in her statement, “ as the wife and daughter of outlaws, misfortune and sadness have not been unknown to me.”
