In an autobiography, a descendant referred to her appearance as "not unlike Holbein's portrait of Bloody Mary with just a touch of Charley's Aunt."^[4]

Lady Berners died at Ashwellthorpe, Norwich on 18 August 1917.^[13] As her eldest son predeceased her, the barony passed to her second son, Sir Raymond,^[3] who had already inherited the Tyrwhitt baronetcy upon her husband's death in 1894.^[2]

Through her third son Hugh, she was a grandmother to Gerald Tyrwhitt-Wilson, better known as Lord Berners, the composer, novelist, painter, and aesthete,^[4][14] upon whose death her husband's baronetcy became extinct. The barony, however, passed to her granddaughter, Vera,^[15] the eldest child of her fifth son, Rupert.^[2]

Through her daughter Arden, she was a grandmother to Edward Knollys, 2nd Viscount Knollys, the Governor of Bermuda.^[1]

Through her daughter Sybil, she was a grandmother to Wing Commander Vashon James Wheeler, a British Army and Royal Air Force officer who served as an infantry officer in both the First World War and the North Russia intervention, and then as a fighter and bomber pilot in the Second World War.^[16]
