Prayer was always an integral part of Moreen’s life. She prayed frequently, supporting her family. Her love of family, people, friends, music, and belief in God’s goodness sustained her in times of trial throughout her life. Moreen was a member of St. Malachy’s Catholic Church, where she belonged to Circle 13.
