To better know the soon-to-be Blessed Zelie and Louis, please read the The Story of a Family (written by Abbe Trochu and republished by Tan Books and Publishers), which includes actual letter excerpts from Zelie. It is truly a treasure-trove of (and for) a Catholic family. The Martins lived a very quiet but active interior life, one considered 'unique' and, by the less charitable, 'rigid.' Yet the passage of time has proven that the Martin parents practiced the virtues to a heroic degree, which is always the mark of sanctity.
