Anna Sophie Magdalene Frederikke Ulrikke
Anna Sophie Magdalene Frederikke Ulrikke (born in 1730 or 1740 – died 22 January 1805) was a Danish con artist who in 1766 demanded a pension from the Danish royal house with the claim that she was the illegitimate daughter of King Christian VI of Denmark and the king's sister-in-law, the Dowager Princess of Ostefriesland, Sophie Caroline of Brandenburg-Kulmbach (1707–1764).
Sophie Caroline of Brandenburg-Kulmbach had lived at the Danish court as a widow after 1735, and it was a widespread rumour that she had a relationship with her brother-in-law.
Anna's story was backed up by a Norwegian student, Kirchhof, who was her lover.
In 1770, a commission was organized to examine the case.
After it was discovered, that Anna had been a prostitute in Amsterdam, her claim was deemed false, and she was placed in Mons Chastity House.
She was later released for good behaviour and given a pension of $100.
Her date of birth is given as either 1730 or as 1740.
