Anna Charlotta was born daughter of the wealthy Christoffer Lorentz von Stapelmohr and Maria Lucretia Dittmer: her father was director of the sea customs and was ennobled in 1756.

The reason for the changed behavior of her husband was said to be the king: during a political disagreement, Gustav III, made a remark about her childless marriage and her latest interest in Bruse, one of his stable masters, upon which she answered him: "Your Majesty, we can not afford to keep an equerry"[2] This remark deeply offended the King, who quite correctly took it as a remark about his and the queen's rumored relationship with the royal stable master, equerry Count Adolf Fredrik Munck af Fulkila: the rumor at the time claimed that the King had asked Munck to impregnate the queen.

She gave birth to a daughter on Christmas day 25 December 1790 and died shortly after the childbirth 1 January 1791, "of sorrow" according to the gossip.

In 1796, Elsa Fougt gave a memorial speech to her in the order Stora Amaranther-orden: Court and city admired her exquisite taste, her playful mind.

So passed some happy years, by which she, flattered by everyone's applause and safe by the nature of her own good heart, free from sorrow abandoned herself to the shining pleasures of the grand world.

[3]Her daughter, Charlotte Schröderheim, was raised as a foster-child at the home of her close friend, Beata Elisabeth Théel (1744–1805).
