Her father became a revolutionary in the Republic of Mainz from 1792 until his death in 1794, while her mother lived in the Neuchâtel area with her lover and eventual husband Ludwig Ferdinand Huber.
The family moved to Tübingen, Stuttgart and Ulm, where her stepfather died in December 1804, when she was already engaged to the forester Gottlieb von Greyerz [de].
[19] Her mother then left Mainz for Strasbourg in December 1792, accompanied by her daughters and the Forsters' lodger, Thomas Brand.
[21][22] In November 1793, Georg, who had gone to Paris as representative of the Mainz Republic,[23] managed to come to Travers, where he stayed with his wife and children and Huber for a few days.
[29] When Huber obtained editorial positions at Johann Friedrich Cotta's Neueste Weltkunde and then the Allgemeine Zeitung in 1798, the family moved to Tübingen and then to Stuttgart.
[33] The 27-year-old Gottlieb von Greyerz became engaged to 14-year-old Claire; Huber was on a journey to Leipzig and Berlin and consented in a letter.
[6] The von Greyerz children played with and were sometimes educated together with Hortense's son Louis-Napoléon, who later became Napoleon III of France.
[5] Her report, which has been described both as "somewhat trivial"[5] and as among "the most vivid and detailed descriptions of life at Arenenberg",[53] was published in the Unterhaltungsblatt für und von Frauen in May 1838 and re-published in the Thurgauer Jahrbuch [de] in 1941.
[6] According to Billon-Haller, the von Greyerz papercuts are poetic, allegoric or romantic and include beautiful landscapes.
[6] There are also domestic scenes and antique or mythological themes present in her work,[6] as well as Biblical or Indic motives that she had encountered while reading.
