Jean Mary Ogilvie (1920–1997) was evidently an extremely talented draughtsman and designer. Her professional life is unknown and scant biographical details that are available revolve around the men in her life. She was the daughter of Charles Struthers White Ogilvie (1891–1936) of Delvine estate, Murthly, Perthshire. Charles was born in Malaysia and died prematurely aged forty-four in Ipoh, Perak. It appears that Jean then moved to her maternal family seat at Gidleigh Park, Chagford, Devon, where she was probably residing when she produced these drawings.
In 1949 she married Major Denys Lyonel Tollemache Oppé (1913–1992) who was educated at Winchester College and Trinity College, Cambridge. He gained the rank of Major in the Second World War and was appointed MBE in 1945. The couple had four children born in the 1950s.
