Prince Ferdinand of Orléans was born on 12 July 1844. He was the son of Prince Louis, Duke of Nemours, and Princess Victoria of Saxe-Coburg and Gotha, cousin of Queen Victoria. Among his siblings was older brother Prince Gaston of Orleans, Count of Eu, the Imperial consort of Brazil (through his marriage to Isabel, Princess Imperial of Brazil), and younger sister Princess Marguerite Adélaïde of Orléans, wife of Prince Władysław Czartoryski. His paternal grandparents were Maria Amalia of Naples and Sicily, Queen consort of the French, and King Louis Philippe, who was forced to abdicate after the outbreak of the French Revolution of 1848. His maternal grandparents were Prince Ferdinand of Saxe-Coburg and Gotha and Princess Maria Antonia Koháry.

Before their marriage, she had been engaged to King Ludwig II of Bavaria, but the King called off the engagement before the marriage. The year after their marriage, the ducal couple moved into Bushy House in the Teddington area of Southwest London. The couple had two children: Louise d'Orléans (1869–1952), who married Prince Alfons of Bavaria (1862–1933) and had children.
