The Three Sisters, Sr. Xavier Tronchain, Sr. Seraphine Ducordeau and Sr. Dorothy Chevrier set sail from Reunion on 28th December with 110 piasters in their purse and landed in Pondicherry in January 1827. The Government opened a free school and a boarding school for European girls on 12th February 1827of which the sisters took charge of. They were taught Reading, Writing and Grammar, Arithmetic, History, Geography, Mythology, needle work, Stitching, Embroidery, and artificial Flower making, weaving and Lace making etc. Art and Music were also encouraged. This was our first technical school in India and the primary school still exists under the title of Pensionnat de Jeunes fillie.
Sr. Seraphine, the first Superior died at her young age of 21 and was replaced by Sr. Xavier. Initially there were a lot of prejudices and misunderstandings among the authorities on the sisters and their mission. In July 1829, Mother Rosalie made her first visit to Pondicherry and stayed for two and a half months putting things in order. She found a fervent, zealous Community, distinguished for its spirit of poverty. Eventually a healthy atmosphere was soon restored among the authorities.
