She was the daughter of Juan José Duarte, a Spaniard from Vejer de la Frontera in Southern Spain, and Manuela Díez Jiménez, a white Dominican or Criollo woman from El Seibo.

Manuela Díez, natives and our parishioners were her godparents Mr. Manuel Ferrer and his wife Vicenta de la Cuebas to whom I warned of their obligations and spiritual kinship: Tgos.

That I attest to.Influenced by her brother's ideals, Rosa devoted her life to his patriotic cause, becoming an active member of the political and military, independentist secret society called La Trinitaria.

Rosa and her group of friends participated in plays performed at a building that used to be an old jail --Cárcel Vieja--, located next to Borgellá Palace, in front of Parque Colon.

Her notes, a contribution of incalculable value to our country, are considered by Emilio Rodríguez Demorizi as the "New Testament" of the history of the Dominican Republic, since through this document the details of those years of conspiracy and work for the liberation of the Homeland.

One said example included when Francisco del Rosario Sánchez, who was sent to San José de los Llanos on a patriotic errand before Vicente Celestino Duarte, and there he learned of that Charles Rivière-Hérard, the new president of Haiti, had issued a national manhunt for the Trinitarios.

Realizing that the life of his leader and best friend was in danger, he mounted his horse and left for the capital with the decision to save Duarte or die in that patriotic purpose, unmatched expression of human solidarity.

In relation to Juan Pablo's stay in this place, Rosa Duarte specifies: "The days he spent there were not so bitter, because, although his parents and family were unaware that he was there, he enjoyed contemplating them at times and their sight mitigated the regret of his hazardous situation."

The raids on the Duarte-Díez house, searches of Don Juan José's warehouse, the home of José Díez's maternal uncle, the tenacious persecutions against other patriots, created a true state of siege; In the midst of everything, Juan Pablo manages to survive, his life, his family, his companions in the patriotic cause are saved, until the favorable action of the Haitian officer Hipólito Franquil, Duarte's Freemason brother, and the "repentant" Dominican traitor himself who reported to Duarte that a price had been put on his head.

Throughout the process to create the Dominican state, Rosa Duarte was a permanent collaborator, but after the Republic was proclaimed, she suffered political persecution from the government of President Pedro Santana and was then expelled from the national territory with her family.
