The prolific volumes of literary works are now of academic interest only, mainly to flesh out aspects of the culture of the time, which embraced a period in which tensions that were to explode in the French Revolution five years after his death were still held in check.

The family retained the seat at Cayx, and the beautifully sited old chateau was where Jean-Jacques and his brother were reared; as a young man he styled himself Lefranc de Caix.
When Louis died in 1745, Jean-Jacques, who had by then served for fifteen years as a general advocate at the court, although expected to succeed him in turn, was not yet old enough to be awarded the position, and had to wait until early 1747 to take over its presidency.
