De La Trémoille family

The House of La Trémoille is an old French family which takes its name from a village (now La Trimouille) in western France. They are related to the Princely Family of Ligne. The family has been known since the middle of the 11th century, and since the 14th century its members have been important in French history.
The main line were known as the Viscounts of Thouars (they were made dukes in 1563), who also used the title Prince of Talmont as well as Prince of Tarente. Men in the family also used the title of Dukes of La Trémoille but more often than not Duke of Thouars was used.
