Bampfylde's first wife was Cynthia Rachel Lascelles. They married in 1910. She was the daughter of Hon. Gerald William Lascelles by his wife Constance Augusta Mary Fitz Clarence Phillipson, a younger son of the
Earl of Harewood. She is remembered by North Molton residents as having hired buses to take the local children to Woollacombe Beach in the summer and to pantomimes in Exeter at Christmas. She died in 1961. In 1962 he married Barbara Pitcairn Nicol, daughter of Peter Nicol of Kirkintilloch, Scotland. He had two children by his first wife. . The memorial stone bench to his father the 4th Baron Poltimore sits at the base of the large tree. The roof of an outbuilding of Court House, the Bampfyldes' manor house, is visible behind the garden • Their only son and heir apparent, Hon. (Coplestone) John de Grey Warwick Bampfylde (1914–1936), was an officer in the Royal Horseguards, who died aged 23 in a horse-racing accident shortly after representing his country as a member of the
1936 Berlin Olympic Games fencing team. A memorial black and white photographic portrait of him in full military dress exists in the Bampfylde Chapel of North Molton Church. The Bampfylde Memorial Garden in North Molton churchyard was created in his memory, being a walled and sunken lawned garden, in the centre of which stands his gravestone inscribed as follows:
In memory of Coplestone John de Grey Warwick Bampfylde, Royal Horse Guards, beloved only son of the 4th Baron Poltimore. Died 3 October 1936 in his 23rd year. So he passed over and all the trumpets sounded for him on the other side. In recent years the garden has received burials of villagers of North Molton, as space in the churchyard has become scarce. • Their daughter, Hon. Sheila Margaret Warwick Bampfylde (born 1912, died 1996), married
Sir Dennis Stucley, 5th Baronet (1907–1983) of
Affeton Castle and
Hartland Abbey in Devon, by whom she had children, including a son and heir,
Sir Hugh George Copplestone Bampfylde Stucley, 6th Baronet (born 1945), and a daughter
Chryssie Lytton Cobbold, Baroness Cobbold (1940–2024). ==Emigration to Rhodesia==
