The Ursuline Sisters Celebrate in Thanksgiving for 475 Years of Service Here it is Thanksgiving Day and the 475th Anniversary of the Founding of the Ursuline Sisters. We have much to be thankful for: our lives, our health, our family, our friends, our community. In a particular way this year we are grateful to God for this anniversary. There is no word that immediately comes to mind for a 475th anniversary. If you were to make one up from Latin roots, you might say we are celebrating our dodransquincentennial, a word that means 1/4 century less than 500 years. No matter what you call it, 475 is a long time. People mark anniversaries for 2 reasons: to look back and to look ahead. What we remember is pretty well known to most of us…Sr Mary McCormick’s reflection for 475th Anniversary Nov 25 2010 Local news coverage
