This is probably Henriette Pyvart de Chastillé who had two children who reached adulthood, François and Alexandre. Alexandre married Joséphine Tascher de la Pagerie who bore him a son, Eugéne, and a daughter, Hortense. Eugéne became Duke of Leuchtenberg and married Princess Augusta of Bavaria. He and Augusta bore six children who survived to adulthood:
• Joséphine Maximiliane Eugénie Napoléonne de Beauharnais (1807–1876); married Oscar I of Sweden, himself the son of Napoleon's old love, Désirée Clary
• Princess Eugénie Hortense Auguste de Beauharnais (1808–1847); married Friedrich, Prince of Hohenzollern-Hechingen
• Prince Auguste Charles Eugène Napoléon de Beauharnais, 2nd Duke of Leuchtenberg (1810–1835); married Maria II of Portugal. There was no issue
• Princess Amélie Auguste Eugénie Napoléone de Beauharnais (31 July 1812 – 26 January 1873); married Pedro I of Brazil (father of Maria II of Portugal and Pedro II of Brazil) and became Empress of Brazil
• Princess Theodelinde Louise Eugénie Auguste Napoléone de Beauharnais (1814–1857); married Wilhelm, 1st Duke of Urach
• Prince Maximilian Josèphe Eugène Auguste Napoléon de Beauharnais (1817–1852); married Grand Duchess Maria Nikolaievna of Russia, eldest daughter of Nicholas I of Russia, and received the title of "Prince Romanovsky" with the style "Imperial Highness," in 1852.
Henriette's son Alexandre died and daughter-in-law Josephine went on to marry Napoléon Bonaparte. Alexandre's daughter Hortense became Queen of Holland while Napoléon was in power.
