Léonie Martin was the least gifted of the four sisters of St Thérèse of Lisieux. She was an emotionally disturbed child who caused anguish in her family. Her mother, Zélie Martin, suffered most of all. Marie Baudouin-Croix, well-known French poet, has examined Zélie s correspondence with her daughters, sister, brother and sister-in-law. We see the difficult child, the despair of many, who was the first to follow Thérèse’s Little Way. It was only after three valiant but unsuccessful attempts that Léonie was finally accepted by the Visitation Order at Caen. She succeeded in conquering a tough temperament, so that by the time of her death in 1941, at the age of seventy-eight, she was regarded as a saint and the convent at Caen was inundated with letters testifying to her posthumous aid.
