Born on December 8, 1929, in Wayside, Maryland, Cecelia (known as “Tinkie”) was the daughter of the late John Albert Maddox and Mary Louise Maddox. She was one of twelve children, growing up alongside six brothers and five sisters in a close-knit family that remained important to her throughout her life.

Through the years, the company underwent several name changes before becoming Beretta USA. Her dedication, professionalism, and strong work ethic earned the respect of colleagues and friends alike. She retired in 1993 after many years of faithful service.
Outside of work, Cecelia found joy in many pursuits. She loved dancing, gardening, reading, and sewing, and she was always busy with a variety of hobbies and projects. She took great pride in her home and family and was happiest when surrounded by those she loved.
