Louis Otto, Prince of Salm

Family

Louis Otto married Princess Albertine Johannette of Nassau-Hadamar on 20 July 1700. She was a great-granddaughter of John VI, Count of Nassau-Dillenburg, brother of William the Silent. The couple had three children:

Dorothea Franziska Agnes ; married Nikolaus Leopold, Prince of Salm-Salm, who became the Prince of Salm-Salm, and has many descendants from his 18 children, including Princess Rosemary of Salm-Salm and Princess Isabella de Croÿ.
Elisabeth Alexandrine Felicite Charlotte Gotfriede ; married Claude Lamoral, 6th Prince de Ligne and had issue.
Christine Anna Luise Oswaldine ; married Joseph, Hereditary Prince of Hesse-Rotenburg; their eldest daughter Viktoria married Charles, Duc de Rohan-Rohan, the last male of the Soubise cadet branch of the French princely House of Rohan.

After the death of his aunt Anne Henriette of Bavaria, Princesse of Arches, he was opposed by his brother-in law, the Duke of Ursel. Eventually the duke obtained the rights to the principality, and his descendants still hold the title Prince d'Arches et de Charleville.
Ludwig Otto died in Anholt Castle in 1738. His death ended his branch of the House of Salm, since Ludwig Otto had no son as heir.
