In 1930 and 1931 H. T. Guest was listed as resident at Ashton Gifford House. The house was occupied from at least 1931 (until his death) by the Irish peer Lord Headley - Rowland Allanson-Winn, 5th Baron Headley. Lord Headley is sometimes referred to as the first Muslim peer of Britain (a misnomer, as he was actually the second). He was President of the British Muslim Society, and died in 1935. Lord Headley's widow (his third wife), Lady Catharine Headley (née Lovibond), continued living at Ashton Gifford House until 1940, when she shared the house with Greenways School. Lady Headley opened the gardens to the public in aid of the Queen's Institute and district nursing under the National Gardens Scheme
