The Desdunes of New Orleans are indeed direct descendants of the Rossignol-Desdunes family of Saint Domingue and Saint Christophe. The author of the Louisiana branch is Jeremie Desdunes, a free mulatto or quadroon who fleed the island during the evacuation of Saint Dominuge. He repaired to Cuba where he marriedaSpanish woman by the name of Henrietta. They were the parents of Rodolphe Desdunes, the famous writer and civil rights proponent of New Orleans. He was married to Mathildecheval ( or chaval). They were parents to numerous children who seemed to have had a large descendancy in Louisiana.
Should you be a descendant of this couple, you can confirm your Haitian ancestry in the Rossignol Des Dunes family of Saint Domingue. Nevertheless,"The Saint Domingue Epic", or the story of the Rossignol Des Dunes and family alliances does not necessarily address de Desdunes offsprings of the family.
Another Desdunes descendant of Haiti was sent by the government of Faustin Soulouque as plennipotentiary minister in New Orleans to negociate with the local government the possible repatriement of several creole families of Haitian ancestry. The negociations had failed.
