A very good anecdotal book on the St-Domingue revolutionary period was written by a certain Descourtilz. This book is very rare, it's title is: ''Voyage d'un naturaliste en Hayti''. It contains lively anecdotes on the Rossignol-Desdunes family. Some members of the family opposed to the emancipation movement, were suspected to have pactised with the British against France to deliver the St-Marc Gonaives area under their arms. When the Bristish were defeated by the Toussaint troops,their possessions were ceased, and those involved fled. Several family members however did not flee, some even embraced the revolutionary ideas and were close to Toussaint Louverture like 'la Veuve Descahaux, aunt of Descourtilz'. Descourtilz was apparented to this family and tried to have Veuve Descahaux intercede in his favor to recuperate some of the ceased properties.
Another book that relate some of this family relatives is : 'Sur les rives du passé'. Based on these anecdotal information one could tentatively establish the following links (this is not hard data).
