Taglioni was married to Comte Auguste Gilbert de Voisins in 1835, but separated in 1836. She later fell in love with Eugene Desmares, a loyal fan, who had defended her honour in a duel. Desmares and Taglioni gave birth to a child in 1836. Three years later Desmares died in a hunting accident. In 1842 she gave birth to her second child. It is unknown who the father is even though the birth certificate states the father as Gilbert de Voisins. Taglioni's children's names were Georges Philippe Marie Gilbert de Voisins and Eugenie-Marie-Edwige Gilbert de Voisins.
Training
Taglioni moved to Vienna with her family at a very young age where she began her ballet training under the direction of Jean-Francois Coulon and her father. After Filippo was appointed the ballet master at the court opera in Vienna there was a decision that Marie would debut in the Habsburg capital. Even though Marie had trained with Coulon, her technique was not up to the standards that would impress the Viennese audiences. Her father then created a rigorous six-month training regimen for his daughter where she would hold positions for 100 counts. The training was conducted daily and consisted of two hours in the morning with difficult exercises focusing on her legs and two hours in the afternoon focusing on adagio movements that would help her refine poses in ballet. Taglioni had a rounded back that caused her to lean forward and had slightly distorted proportions. She worked hard to disguise her physical limitations by increasing range of motion and developing her strength. Taglioni focused her energy on her shape and form to the audience and less on bravura tricks and pirouettes. In Vienna, Marie danced her first ballet choreographed by her father titled "La Reception d'une Jeune Nymphe Ă la Cour de Terpsichore".
In 1837 Taglioni left the Ballet of Her Majesty's Theatre to take up a three-year contract in Saint Petersburg with the Imperial Ballet. It was in Russia after her last performance in the country and at the height of the "cult of the ballerina", that a pair of her pointe shoes were sold for two hundredrubles, reportedly to be cooked, served with a sauce and eaten by a group of balletomanes. In July 1845, she danced with Lucile Grahn, Carlotta Grisi, and Fanny Cerrito in Jules Perrot's Pas de Quatre, a ballet representing Taglioni's ethereal qualities that was based on Alfred Edward Chalon’s lithographic prints. Pas de Quatre was originally choreographed to be presented to Queen Victoria, who attended the third performance.
Taglioni died in Marseille on 22 April 1884, the day before her 80th birthday. Her body was moved to Paris. There is some debate over whether she is buried in Montmartre or in Père Lachaise, or if the grave Montmartre site belongs to her mother. The local dancers began leaving their worn pointe shoes on the Montmartre grave as a tribute and thanks to the first pointe dancer.
