Alexandrine Marie Malvina Élise (b.1799)
Napoléon Louis Frédéric (b.1800)
Regarding the children. I figure Marie Victoire is a wedding-night baby. Bonaparte's soldiers referred to Josèphine as the Notre Dame des Victoires IIRC, so it seems likely to me, that Napoléon will somehow insert this into his daughter's name. Victoire and Hortense will be the apple of their dad's eye. Hortense first, since she's older, but Victoire because she's Napoléon's own child. Her other names, Letitie, is for Madame Mère and Catherine is for Josèphine's deceased sister (whose death sent her to France).
His eldest son, I reason that Napoléon will name the boy after his own dad (hence the Charles as a first name), then himself, Alexander the Great, and Joseph can alternately be ambiguous, as it can be for Josèphine, his uncle, Joseph, or Josèphine's dad (Joseph Gaspard Tascher de la Pagerie).
The second daughter is named Alexandrine because of the dad's Egyptian campaign. I was gonna go with Cléopatre but I thought that that would be far too exotic, even for Egyptomanic France. So named for Alexandria is the next best thing. Malvina is after the character in Ossian. Napoléon was an Ossian fanboy, even giving one of their names to two of his godsons (Dermide Leclerc and the future Oscar I of Sweden), so why not Malvina for his own daughter? Especially since Oscar-Malvina are a pair of lovers in Macpherson's cycle.
The second son I couldn't decide if he should die in infancy or be stillborn (or if there should be another stillbirth after 1800). I was also toying with a classical name for him, but wasn't sure what to use. Alexandre's already been used, and César or Auguste seem unnecessarily pompous (particularly for a second son). I contemplated Roland/Orlando, but I'm not sure if that was fashionable at the time. So I'm open to suggestions.
