Maud Lilburn MacLellan OBE (6 October 1903 – 21 May 1977) was a Scottish commanding officer of the First Aid Nursing Yeomanry (FANY).

[3] Helen Gwynne-Vaughan was made Chief Controller of the newly formed Auxiliary Territorial Service (ATS) in 1939.

[4] This was a role that Mary Baxter Ellis had turned down, but she agreed however to supply 1500 women to serve with the ATS as long as they could be independent.

[4] MacLellan was placed in a difficult position but she opted to join the ATS and lead the 4th Scottish motor company from November 1938.

Princess Elizabeth was keen to learn how to drive and the ATS was chosen to supply a three week course which included map reading and mechanics.
