Katherine Gregory Thomas (1898-1994) was born into a family known for their significant role in the development of the oil boom in Western Pennsylvania. Despite her Pennsylvanian roots much of her early life centered around Washington, D.C. Known as Kay, she attended National Park Seminary, a finishing school for well-to-do young women famous for its impressive and eclectic architecture. Mrs. Thomas devoted much of her time to philanthropic efforts, especially to causes in Washington, DC; she gave generously to the St. Albans school and bequeathed one of the largest ever monetary gifts to the National Cathedral. In the 1930s, Mrs. Thomas and her husband, attorney Charles McGill Thomas, moved to "Windy Knoll," a 250-acre dairy farm in Maryland, where she remained the rest of her life.
Mrs. Thomas' emerald ring was acquired from Galt & Bro. Inc. Opened in Washington, D.C. in 1802, Galt was one of the oldest jewelry stores in the US before closing its doors in 2001. Galt counted many notable historical figures as patrons including Abraham Lincoln, J. Edgar Hoover, Eleanor Roosevelt and John F. Kennedy.
