Lady Alexandra Margaret Elizabeth Douglas-Home (née Spencer; 4 July 1906 – 26 May 1996) was an English musician, writer, and arts promoter.
Lady Margaret was mainly educated at home under a governess, but spent some time at Northampton Secondary School for Girls, attending events such as concerts at the Albert Hall.
She then accompanied Princess Alice, Countess of Athlone to South Africa as a lady-in-waiting, before resuming her music studies in Vienna.
This led her in 1974 to found Burnham Market Festival, which began as a series of concerts, poetry readings and drama productions.
Their daughter Fiona married first Gregory Martin and secondly the merchant banker Sir Ian James Fraser (1923–2003), former chairman of Lazard.
