Maria Feodorovna (Sophie Dorothea of Württemberg)
Born Duchess Sophie Dorothea of Württemberg, she was a daughter of Friedrich II Eugen, Duke of Württemberg and his wife, Friederike Dorothea of Brandenburg-Schwedt. She belonged to a junior branch of the House of Württemberg and grew up in Montbéliard receiving an excellent education for her time and station. In 1776, when Grand Duke Paul (the future Paul I of Russia), became a widower, Sophie Dorothea was chosen by Frederick II of Prussia, her maternal great uncle, and by Empress Catherine II of Russia, as the ideal candidate to be Paul’s second wife. They met in a state dinner in Berlin and their engagement was quickly arranged.

Conversely, Anthony Camp challenges the belief that Sophia had a child and provides a detailed summary of the available evidence. In his book "Royal Babylon: the Alarming History of European Royalty", author Karl Shaw writes of the possibility that the Duke raped his sister, citing evidence from Charles Greville's diaries, as well as other factors. Historian Gillian Gill believes that Sophia secretly gave birth to the child and that this is the reason Sophia never married. Alison Weir and others, however, write of a possible marriage between Sophia and Garth the same year as the child's birth, but there is no evidence to back this assertion other than the presence of a wedding ring in a portrait of an aged Sophia.
