His three sons, Pierre, Michel and Gilles, were ennobled together by letters patent from King Henry III of France on 12 January 1587.

[2] In 1692, Gilles-François de Maupeou inherited the town of Ableiges, which he developed and promoted to great success.

The Maupeou family came to prominence with René Nicolas, Keeper of the Seals and last Lord Chancellor of the Ancien Régime, under the reign of Louis XV of France.

In 1771, René Nicolas de Maupeou, then Chancellor since 1768, exiled 130 members of the Parlement in what amounted to a coup d'état to take back the judiciary,[3] thus restoring King Louis XV of France's authority over political reforms.

At the time, the Dauphin, the future Louis XVI of France, approved the Chancellor's reforms despite a wave of hostility from the higher nobility and magistrates.
