D'Ornano was born in Ajaccio, Corsica on January 17, 1784. He was a son of Lodovico Antonio d'Ornano and Isabella Maria Buonaparte. His paternal grandparents were Filippo Antonio d'Ornano and the former Maria Geronima Maggioco. His maternal grandparents were the former Maria Rosa da Bozzi and Napoleone Buonaparte, making him a second cousin of Napoleon Bonaparte.[1]
He returned to France and resumed active service in 1829 when he was given a position at the Military Academy of Saint-Cyr. In 1830, after the July Revolution, he was given command of the 4th military division at Tours. Two years later, he suppressed revolts in the Vendée after which he was made a Peer of France. In 1848 he served as head of the 14th military division until he resigned for reasons of health.
In 1816, d'Ornano married his longtime lover, Countess Marie Walewska (née Łączyńska), the former wife of Count Athenasius Colonna-Walewski, whom she divorced in 1812. After their marriage, they settled in Liège as d'Ornano did not want to return to Paris due to his pro-Napoleonic allegiances. From her prior marriage, she had several children, including Count Antoni Colonna-Walewski. Another son, rumoured to be from her relationship with Napoleon, was Count Alexandre Joseph Colonna-Walewski. Before her death during childbirth in 1817, they had a son, Rodolphe-Auguste d'Ornano:[2] The line of Counts d'Ornano was continued by his only son and exists until the present day.
After the death of his wife, her heart was placed in the crypt of the d'Ornano family at Père Lachaise Cemetery in Paris and her body was brought back to Poland for burial.[2][a] He died in Vincennes, a suburb of Paris, in 1863.[3]
