In 1793, members of the Blin de Bourdon family, among others wrongly accused for having fled the country, are imprisoned.  In February of 1794, Françoise is arrested, instead of her grand-mother, and taken to prison in Amiens.  It is only after the death of Robespierre that they will all be freed on the 3rd and 4th of August 1794; Françoise then rejoins her brother at the Blin town home in Amiens.
