Overview
Charlotte Wilhelmine Christiane Marie of Hesse-Darmstadt (5 November 1755, Darmstadt – 12 December 1785, Hanover), was by marriage Duchess of Mecklenburg-Strelitz.
Life
Charlotte was a daughter of Prince George William of Hesse-Darmstadt (1722-1782) from his marriage to Countess Maria Louise Albertine of Leiningen-Falkenburg-Dagsburg (1729-1818), daughter of Count Christian Karl Reinhard of Leiningen-Dachsburg-Falkenburg-Heidesheim.
The princess was first engaged with the hereditary prince Peter Frederick William of Oldenburg, but the engagement was dissolved again as a result of the onset of Peter's mental illness.
Charlotte married Charles of Mecklenburg-Strelitz (who later became the Duke of Mecklenburg-Strelitz), on 28 September 1784 in Darmstadt. He was previously married to Charlotte's older sister Friederike, who had died in childbirth. She thus became stepmother for her sister's five surviving children - her nieces and nephews.
