Johanne Nielsdatter, also known as Johanne Nilsdatter, was a Norwegian woman who met a tragic end as the last confirmed victim of witchcraft execution in Norway. Hailing from Kvæfjord in present-day Troms county, little is known about her life except for the events leading to her arrest and trial. Accused of renouncing her baptism and religion in favor of a personal demon named Knut and the ability to use magic, she confessed to causing sickness, death, and even influencing the weather through her alleged magical powers. Subsequently, she was found guilty and sentenced to be executed by burning. While she was the last person confirmed to have been executed for sorcery in Norway, the use of burning as an execution method persisted for bestiality until at least 1757. Despite more witch trials in the 18th century, none resulted in death sentences or lack adequate documentation. The law against witchcraft was ultimately abolished in 1842, marking the end of a dark chapter in Norwegian history.

Johanne Marie de Malleville (1750-1817) was a prominent figure in the court of Denmark as a favorite of queen Caroline Matilda. Born to captain Emanuel Meyer and Johanne Mohlholm, she married captain Thomas de Malleville in 1763. Following the queen's affair with Struensee in 1770, a reform was implemented, allowing non-nobles to dine with the royal family. Malleville, a non-noble woman, became a personal friend and favorite of the queen, frequently accompanying her at court events and informal dinners. However, her presence at court and association with the queen's circle of friends caused quite a scandal in conservative circles. After the fall of Struensee in 1772, Malleville's spouse was involved in his arrest, leading to his appointment to the colony of Saint Thomas in the Caribbean. Malleville remained in Copenhagen and later divorced her spouse due to infidelity, marrying count Verner Schulenburg in 1781. Her intriguing life and significant role in the Danish court have been documented in various historical references, including August Fjelstrup's "Damerne ved Karoline Mathildes Hof" in 1909. Johanne Marie de Malleville's influence and relationships within the royal court provide a fascinating glimpse into the dynamics and intrigue of 18th-century Danish society.
