The daughters of famed Wolverhampton photographer, Arthur Bennett Clark and his wife, Agnes, Violet and Mabel were both involved with the Red Cross during the First World War. Mabel was born in Wolverhampton on 16 December 1891, and Violet was born in Wolverhampton on 14 July 1898
In 1901, the family were living at Ivydene, Eagle Street, Upper Penn, Wolverhampton. They were at the same address in 1911, by which date Mabel had become an Art student, and they were still both living at Ivydene during the First World War.
During the war, Violet served as a nursing member at the VAD hospital in Tettenhall, from September 1917 until March 1919. Mabel also served as a nurse at Sandon Hall Auxiliary Hospital, from March 1916 until April 1917.
Mabel married Arthur T. Vernon in Wolverhampton in 1917, which is presumably why she ceased her nursing duties. By 1939 they were living in Seisdon with their two children Jean R. and Arthur K. Mabel died in Seisdon in 1971.
In 1928, Violet married John I. Ennis in Wolverhampton. She died in Cheltenham in 1968.
