They both lived in Adelaide, South Australia. The website http://www.familytreeoz.com/ has published indexes of early South Australian car registrations from 1906-1927 and a list of 1910 car owners and members of the South Australian Auto Club.
Arthur Murray Cudmore registered an 8 horsepower Darracq in 1906. He received the numberplate SA 4. He passed the numberplate on to his daughter, my grandmother, Kathleen (1908-2013). This number plate stayed in the family until 2012. It was sold because no member of the family lived in South Australia any more.
Kathleen wrote an article in 1967 about number plates and her father's early cars.

It was considered both luck and good management that the car did not hit either of the gate posts as it came in. However, it did run into the garden bed just inside.The Darracq owned by Dr A.M. Cudmore was painted with vertical stripes, one and half inches wide, in black and green.

In a History of the Royal Adelaide Hospital a short biography of Sir Trent de Crespigny remarks:
It is said that he was very interested in motoring, but that driving with him could be a rather hair-raising experience. (Hughes, J. Estcourt A history of the Royal Adelaide Hospital. The Board of Management of the Royal Adelaide Hospital, [Adelaide], 1967. page 166)In 1929 Trent de Crespigny had another car accident that was reported in the newspapers.
