He was an attractive young man of great promise. Like most of his family he went into exile at the beginning of the French revolution, going to London in 1789 where he lived a wild life, his usual 
companions being Creole women. He allowed himself many liberties with people and tolerated the same from them. At one stage he lived with a low-class streetwalker, was seen with her at races, even drove her in his own carriage, took her to the opera and sat by her side. Sometimes he would suddenly realize his undignified position and take refuge in the box of Madame de Boigne; but as he left the Opera House, loud cries of "Berry, Berry!!" were heard; it was his notorious 'protegie' 
calling for him to fetch the carriage. 
However, while in England he met Amy Brown and it was later claimed that they married in 1804 or in 1806 at Kensington, but no proof has ever been found. Several children were born but the Duc de Berry acknowledged only two daughters who, in 1820, were ennobled by his uncle, King Louis XVIII. 
After the restoration of his family he was appointed commander of the troops in and around Paris. In 1816 married Princess Caroline of Naples with whom he was very happy. He fathered several children but only one daughter survived. In February 1820 his Duchess was pregnant when they attended a performance at the Paris Opera House. While leaving, the Duc de Berry was stabbed by a deranged lunatic and Bonapartist, Pierre Louis Louvel. Carried back into the Opera House,he 
died in his wife's arms a few hours later. On 28 September 1820 his wife gave birth to a son which survived and received the nickname of 'l'enfant du miracle'.
