Here are links for two webites with excellent resources about Zélie and Louis Martin, the parents of St. Thérèse of Lisieux, who are to be beatified this coming Sunday.
Maureen O'Riordan's Thérèse of Lisieux website has compiled some useful information for Sunday's beatification. The site's resources include a Press Kit and Maureen's own article with discussion points for group conversation, as well as a downloadable article by Fr. Antonio Maria Sicari about the Martins.
Another St. Thérèse of Lisieux website has The Story of a Family (adapted from an earlier article) by Fr. Raymond Zambelli and a page with short lives of each of the Martin parents and other articles, as well as the homily of Cardinal Saraiva Martins on the 150th anniversary of the wedding of Zélie and Louis Martin, July 13, 2008.
