☘️ Rockland County AOH Mourns the Passing of Mary O’Sullivan ☘️
The Rockland County Ancient Order of Hibernians mourns the passing of Mary O’Sullivan, a beloved figure of our Irish American community, a dedicated Hibernian, and a longtime Chairperson of the Rockland County St. Patrick’s Day Parade.
For decades, Mary’s dedication, leadership, and countless hours of volunteer service helped make the Pearl River St. Patrick’s Day Parade the cherished tradition it is today. She helped preserve and celebrate our Irish heritage, strengthen our community, and ensure that our traditions would be passed on to future generations.
Mary was recognized as Hibernian of the Year in 1999 and received one of our community’s highest honors when she served as Grand Marshal of the Rockland County St. Patrick’s Day Parade in 2007.
Mary’s life reflected the finest traditions of Hibernianism: Friendship, Unity, and Christian Charity. Her devotion to her Catholic faith, her family, her Irish heritage, and her community was evident in everything she did.
We extend our deepest condolences to Mary’s family, her many friends, and her sisters in the Ladies Ancient Order of Hibernians.
Each March, when the pipes sound and the parade makes its way through Pearl River, Mary’s legacy will march on.
