The date of MS's birth is unknown, but it was probably some times around the early 1770s.
According to the statement on a later title page, MS published anonymously this year a work entitled Interesting Tales
, translated from German.
She must in all likelihood have died some time after 1805 or early 1806, the time of what is probably her latest identified publication.
By January 1806
MS published what seems to be her final work, a German translation, Domestic Scenes
. Again she identifies herself by earlier titles, as 'the author of Agnes de Lilien, Statira, Restless Matron'.
