Léonie Martin

Léonie Martin, also known as Sister Françoise-Thérèse, VHM (3 June 1863 – 16 June 1941) was a French Catholic nun who led a cloistered life as a member of the Visitation Sisters. She was the daughter of Saints Louis Martin and Marie-Azélie Guérin Martin and an elder sister of Saint Thérèse of Lisieux. She is sometimes dubbed Saint Thérèse's "difficult sister".

Her cause for beatification was permitted to be introduced in the Diocese of Bayeux and Lisieux in 2015, and she has been given the posthumous title Servant of God. Provided by Wikipedia
