The Rosettis were parents to eight sons: Mircea, Ion, Vintilă (journalist and writer), Horia, Elena-Maria, Toni, Floricel and Libertatea Sophia, all of whom were noted for their political activities.
[3] In 1837, her younger brother Effingham was appointed secretary of Robert Gilmour Colquhoun, the British consul in Wallachia; soon after, Mary herself arrived in Bucharest, where she began work as a tutor.
[5] Mary Grant was employed by the family of Wallachian Militia Colonel Ioan Odobescu, and gave lessons to his children—including his son Alexandru, the future writer and politician.
[6] With the Jewish Constantin Daniel Rosenthal, Maria followed the ships on shore; upon arrival, she pointed out to the local authorities that the Ottomans had stepped out of their jurisdiction, persuading the mayor of Sviniţa to disarm the guards, which in turn allowed the prisoners to flee.
[8] Her role in this last stage of the revolution was celebrated by French historian Jules Michelet in his 1851 essay Madame Rosetti,[9] and by her husband, who compared her to Anita, the Brazilian-born wife of Italian insurgent Giuseppe Garibaldi.
[12] In 1878, Maria Rosetti authored a piece for her Mama şi Copilul ("Mother and Child") magazine, in which she offered praise to her deceased friend: "[Rosenthal was] one of the best and the most loyal people that God created after His image.
"[13] During the 1850s, before and after the 1856 Treaty of Paris allowed her family to return to the Danubian Principalities, Maria Rosetti and her husband invested their energies into support for Partida Naţională, calling for Wallachia's union with Moldavia (effected in 1859 by the election of Alexandru Ioan Cuza as Wallachian Prince, and subsequently Domnitor of the two states).
[5] In 1877, as Romania proclaimed her independence and joined the Russian Empire in the anti-Ottoman war, Maria Rosetti rallied funds to aid the wounded, establishing and managing the hospital in Turnu Măgurele.
