La Tour d'Auvergne
Its senior branch, extinct in 1501, held two of the last large fiefs acquired by the French crown, the counties of Auvergne and Boulogne, for about half a century.
Its cadet branch, extinct in 1802, ruled the duchy of Bouillon in the Southern Netherlands from 1594, and held the dukedoms of Albret and Château-Thierry in the peerage of France since 1660.
Bertrand V's grandson Jean III de la Tour d'Auvergne (1467–1501) was the last medieval Count of Auvergne, Boulogne, and Lauraguais.
Among his children, the younger, Antony Raymond, lord of Murat, became the ancestor of the obscure line of la Tour-Apchier, which rose to prominence shortly before its extinction in the 19th century.
Although Frederic Maurice was promised to take rank from the original creation of the duchy of Château-Thierry for Robert III of the Marck in 1527, this could never be effected due to vocal opposition of other dukes-peers.
A grateful Louis XIV honored Turenne with burial at the royal necropolis at Saint-Denis and Napoléon considered him to be the greatest military commander of all times.
Godefroy-Maurice's younger brother, Count Frederic Maurice de La Tour d'Auvergne (1642–1707), was a prominent general in the service of the Dutch.
After their line became extinct in 1732, Bergen devolved upon Count Palatine Johann Christian von Sulzbach (1700–1733), who had married an heiress, Marie Henriette Leopoldine de La Tour d'Auvergne, in 1722.
Godefroy-Maurice's wife, Marie Anne Mancini (1649–1714), best remembered for her literary pursuits and for her patronage of La Fontaine, was a niece of Cardinal Mazarin.
The Duchy of Bouillon and other titles passed to their second son, Emmanuel Théodose (1668–1730), whose fourth wife was Louise Henriette Françoise de Lorraine.
Although officially married to Jules de Rohan, Duke of Montbazon, she had an illegitimate son who died in infancy by her cousin, Charles Edward Stuart, Jacobite claimant to the thrones of England and Scotland.
His only son, Jacques Léopold Charles Godefroy, incapacitated by a road accident, died in 1802, leaving no issue of his marriage to a Princess of Hesse-Rheinfels.
In 1787, the 6th Duke recognized this legendary connection and adopted Philippe d'Auvergne, calling on him to succeed his own son in the case the latter were to die without male issue.
