Louis Martin and Azélie-Marie ("Zélie") Guérin Martin were a French Roman Catholic couple and the parents of five nuns, including Thérèse of Lisieux, a Carmelite nun who was canonized as a saint of the Catholic Church in 1925 and Léonie Martin declared "Servant of God" in 2015. In 2015, the couple were also canonized as saints, becoming the first spouses in the church's history to be canonized as a couple.

The Secular Franciscan Order is the third branch of the Franciscan Family formed by Catholic men and women who seek to observe the Gospel of Jesus by following the example of Francis of Assisi. Secular Franciscans are not like the other third orders, since they are not under the higher direction of the same institute. Brothers and sisters of the Secular Franciscan Order make a spiritual commitment (promises) to their own Rule, and Secular Franciscan fraternities can not exist without the assistance of the first or second Franciscan Orders. The Secular Franciscan Order was the third of the three families founded by Francis of Assisi 800 years ago.
