Marianne O'Keeffe ObituaryPublished by Legacy on Mar. 16, 2026.Marianne Diana (Lugg) O'Keeffe passed away peacefully at the age of 84 on March 12, 2026, at her home in Manitowoc, Wisconsin. A woman of keen intellect, curiosity, and natural elegance, she delighted in beauty in all its forms-in art, literature, gardens, antiques, and in the thoughtful way she moved through the world. Just nine days earlier, she lost her beloved husband of 59 years, Don O'Keeffe. Together they built a life rich in laughter, creativity, and deep devotion to each other.Born on July 3, 1941, in the seaside town of Ryde on the Isle of Wight, England, Marianne's early years were shaped by the challenges of World War II. While her father served at sea as a Royal Navy captain, she and her brother Michael were comforted by his letters-filled with drawings and playful poetry-that nurtured her lifelong love of storytelling and art.Marianne moved to Ireland in 1963 to pursue a master's degree in literature at Trinity College Dublin. Tall, with long blond hair and graceful hands, Marianne was strikingly beautiful. She met Don on her first day in Ireland, and his wit, imagination, and zest for life mirrored her own, forging a bond that endured for more than six decades.After moving to the United States in 1965, Marianne and Don welcomed their son James in 1972. The family first settled in Rye, New York, where Marianne began her career at IBM. She eventually became the executive assistant to the CEO of IBM North America and served as an editor of the company's internal magazine, Think.When Don's naval architecture career brought the family to New Orleans, Marianne embraced a new professional challenge during the early days of the computing era. She completed intensive training to program and install IBM's mainframe computers, applying her formidable intellect, remarkable memory, and strong work ethic to a field far removed from her literary studies. She excelled in the role and found great satisfaction in her work.In 1987, Marianne and Don made Manitowoc, Wisconsin their forever home, where they formed enduring friendships and became deeply woven into the fabric of the community. Marianne cherished the connections she found through her book clubs, English Club, church, and many friendships. Above all, she treasured her son James and his wife Deanna and took immense pride and joy in her grandchildren, Fiona and Elias.Although Marianne left England in 1963, England, in many ways, never left her. She created a beautiful English garden which she lovingly tended. Her soft, musical southern English accent - spoken slowly and always with a smile - was unmistakable. She had a remarkable gift for language, delighting in terms of endearment and often greeting others with a warm "darling."Marianne possessed a rare ability to notice and celebrate the beauty, wit, and charm in everyone she met, bringing joy, laughter, and appreciation into every conversation. Even in difficult times, she met life with quiet strength, elegance, and grace. In countless ways, she made the world around her more beautiful.Marianne is preceded in death by her parents, Reginald and Winifred Lugg, her brother Michael Lugg, and her husband, Don.She will be deeply missed and lovingly remembered by her son James, daughter-in-law Deanna, cherished grandchildren Fiona and Elias, niece Sara (Lugg) Regan and her husband Patrick, great-nephews Will and Luke, her O'Keeffe brothers- and sisters-in-law in Ireland, her many Irish nieces and nephews, and a wide circle of extended family and friends whose lives she touched.A private family funeral service will be held and Marianne will be laid to rest with her husband Don at Evergreen Cemetery, Manitowoc.
