Bets Wiebes lived together with her lover, Bartha Schuurman. When Wiebes started a relationship with Catharina de Haan, the jealous Schuurman knifed De Haan to death.

In 1792 Schuurman was hung from the gallows, whilst the criminal court in Amsterdam exiled Bets Wiebes for six years from the city because she had lain upon another woman "in the way a man is used to do when he has carnal conversation with his wife."
