Early life
Jane Richard was born in Edinburgh in 1958. She is one of four children of the stockbroker John Richard (1933–2003), as well as sororal grandniece of the all-round sportsman Max Woosnam. Her mother, Angela, Lady Buchan-Hepburn (née Scott), was the owner of Kailzie Gardens, an income-generating family garden located in the Scottish Borders. Her parents divorced in the early 1970s and both remarried; her stepmother Christine was a Conservative group leader on the City of Edinburgh Council, while her stepfather was Sir Ninian Buchan-Hepburn, 6th Baronet (1922–1992).
As a child, Jane Richard helped her mother maintain Kailzie Gardens and aspired to become a champion figure-skater, practicing for the Scottish Junior Championships at Murrayfield Ice Rink. She quit when she was 13 and was enrolled at Cobham Hall School in Kent.
