A little bit about Napoleon's family relations:
Napoleon's father was Carlo Buonaparte (alternative spelling)
(1746-1785), a minor Corsican nobleman and practicing lawyer. His mother
was Letizia (or Laetitia) Ramolino Bonaparte (c. 1750-1836).
Napoleon's first marriage, to Marie Josephe Rose (empress Josephine), only lasted until 1809, when it became apparent that she was unable to produce an heir to the throne.
In 1810, Napoleon married Marie Louise (1791-1847, the daughter
of the the
Austrian emperor Francis I. They had a son, Francois
Charles Joseph Bonaparte (1811-1832), who was later to be known
as Napoleon II, even though he never ruled as emperor.
