Anne had two sons:
Louis XIV
Philippe
Louis XIV and his wife Maria Theresa(he died in 1715)
- had one child reach adulthood Louis the Grand Dauphin. Louis died in 1711, 4 years before his father. He was married to Maria Anna of Bavaria
-their eldest son Louis married Marie Adelaide of Savoy. He died in
1712 so while after his father, before his grandfather died
-Louis XV of France-youngest of 3 sons, only to reach adulthood. He
succeeded his great-grandfather.
-his son Louis died in 1765, 9 years before his father
-Louis was the father of Louis XVI, Louis XVIII and Charles X.
-Charles X had one son who went on to have children, Charles Ferdinand, Duke of Berry.
Could go on and on but to simplify. The Duke of Berry had 2 kids who reached adulthood. His daughter Louise married Charles III, Duke of Parma. Louise was the mother of four kids including Robert I, Duke of Parma making her the grandmother of among many others: Xavier (the father in law of Princess Irene of the Netherlands),Zita (grandmother of among others Archduke Lorenz of Austria-Este), and Felix (married the grand duchess of Luxembourg). So through Louise alone the Luxembourg, Belgian and members of the Dutch royal family are descended from Anne. Lichtenstein as well. As well as numerous other non reigning houses.
The Spanish royal house are also descended from her. Philip V of Spain was her grandson. He was the uncle of Louis XV. During the war of Spanish succession he was made king of Spain. The current royals are descended from him.
Anne's second son Philipe was Duke of Orleans. Philipe has the nickname of 'grandfather of Europe'. All the major catholic royal families are descended from him.

It could take hours if not more to describe all of Anne's descendants and lines. But she certainly has an abundance alive among the royal houses.
