Comte Jean du Barry met her among the demi-monde, and succeeded, about 1767, and by the help of his friend Label, the valet de chambre of Louis XV., in introducing her to the King under the name of Mademoiselle l'Ange.

To be formally mistress, a husband had to be found.

The Comte Jean du Barry, already married himself, found no difficulty in getting his brother, Comte Guillaume, a poor officer of the marine troops, to accept the post of husband.

In the marriage-contract, signed on 23d July, 1768, she was described as "the daughter of Anne Becu and of an imaginary first husband, Sieur Jean Jacques Gomard de Vaubernier," and three years were taken off her age.
The marriage-contract was so drawn as to leave Madame du Barry entirely free from all control by her husband.

The marriage was solemnised on 1st September, 1768, after which the nominal husband returned to Toulouse.
Madame du Barry in later years provided for him; and in 1772, tired of his applications, she obtained an act of separation from him.
