Johanne Marie de Malleville (1750-1817), was a favorite of queen Caroline Matilda of Denmark.
After the queen had entered into a love affair with Struensee in 1770, a reform was introduced to allow non-nobles invitations to the royal table, were etiquette was relaxed, and members of the rich burgher class were commonly invited to dine with the royal family.
Johanne Marie Malleville belongs to those non-noble women invited who actually did become a personal friend and favorite of the queen.
After having been introduced at one such informal dinner, Malleville was from that time forward often seen in the company of the queen at the card table and other events at court.
In 1780, she divorced her spouse because of infidelity on his part and the following year she married count Verner Schulenburg.
