Biographical information
According to the archivist Ernest Meininger, Marie Baumgarten was from Nassau-Usingen. This information is due to an uncharacteristic error on his part - he assumed the Baumgarten family was the same as the local Baumgartner family, which originated in Nassau-Usingen. This is not the case - the two families are totally separate, and my research suggests that the Baumgarten family, of which Marie was a member, may have originated in Baden, Germany.

Marie was baptised at St Margaret Westminster, Middlesex, England, on 15 August 1755. Little is known about Marie, however, when she was around 19 years old she attended a boarding school to learn how to manage a household, as was customary for girls like her in England at the time. Occasionally Marie came home to visit her recently widowed father, which was when Gaspard met her and had the opportunity to talk to her, and was attracted by her modest character.

Marie died in Mulhouse, and according to a letter written by a descendant, H. Bretegnier- Desaulles, published with the autobiography of Marie's husband, she died giving birth to daughter Rosine Angelique. Interestingly, this source states she died on 13 April 1798.

A note about Marie's death date:
Most published information says that Marie's death was on 16 April 1798. However, I have translated (from French) the original death record, signed by both her husband Gaspard, and her brother William, which is held with the Archives Départementales du Haut Rhin. The record states that she died at 8 in the evening on the 26th of the month of Germinal (French Revolutionary Calendar), which I believe equates to the 15th of April.
