Saint Margaret of Scotland Church, in Saint Louis. Today is Saint Margaret's feast day in the new calendar. She was sister of the last Anglo-Saxon king of England and wife of the King of Scotland. According to the Catholic Encyclopedia:
In her position as queen, all Margaret's great influence was thrown into the cause of religion and piety. A synod was held, and among the special reforms instituted the most important were the regulation of the Lenten fast, observance of the Easter communion, and the removal of certain abuses concerning marriage within the prohibited degrees. Her private life was given up to constant prayer and practices of piety. She founded several churches, including the Abbey of Dunfermline, built to enshrine her greatest treasure, a relic of the true Cross. Her book of the Gospels, richly adorned with jewels, which one day dropped into a river and was according to legend miraculously recovered, is now in the Bodleian library at Oxford. She foretold the day of her death, which took place at Edinburgh on 16 Nov., 1093, her body being buried before the high altar at Dunfermline.
