Mother Teresa had one sister, who was older.
Mother Teresa was the youngest of the children of a family from Shkodër, Albania, born to Nikollë and Drana Bojaxhiu. Her father was involved in Albanian politics. In 1919, after a political meeting, which left Skopje out of Albania, he fell ill and died when Agnes was about eight years old. After her father's death, her mother raised her as a Roman Catholic. According to a biography by Joan Graff Clucas, in her early years Agnes was fascinated by stories of the lives of missionaries and their service, and by age 12 was convinced that she should commit herself to a religious life. She left home at age 18 to join the Sisters of Loreto as a missionary. She never again saw her mother or sister.
