Eileen was extraordinarily devoted to her all her family, including her sisters, brother, children, grandchildren, and great-grandchildren. She was a devout Catholic and a beloved daughter of God, as evidenced by her commitment to her church, her service, her generosity, and her endless empathy for the people in her life.
