Elizabeth Carrington, born in 1917, sister of Baron Carrington of Upton (known to you and me as Lord Carrington, yes, he who served under Thatcher in the 80s), drove for the LCC Ambulance Service (London Auxiliary Ambulance Service) in 1939. She is listed as living at 50-61 Burton Court in Chelsea.
Elizabeth did not stay long in the LAAS. She joined the Mechanised Transport Corps (a civilian uniformed organisation that provided drivers for government departments and other agencies and drove ambulances) and was attached to the American Ambulance. This service was set up after the evacuation of Dunkirk in 1940 by Gilbert H. Carr. It raised £140,000 from US citizens in London alone. The fund purchased 300 vehicles (ambulances, surgical units and first aid mobile posts and had nearly 400 British women working for them.
In 1943 Elizabeth Carrington married William Lionel Dove, a Liverpool GP serving in the Royal Army Medical Corps. She died in Liverpool in 2004.
