Therese Martin was the last of nine children born to Louis and Zelie Martin on January 2, 1873, in Alencon, France. However, only five of these children lived to reach adulthood. Precocious and sensitive, Therese needed much attention. Her mother died when she was 4 years old. As a result, her father and sisters babied young Therese. She had a spirit that wanted everything.
