Chitty had intended to continue her artistic studies, but chose instead to train as a secretary in order to contribute to the war effort during the First World War. She then worked at the General Post Office in London for a short period of time, before serving as a member of the Women's Land Army in her home county of Shropshire for the rest of the war. The Women's Land Army was a civilian organisation created so that women, nicknamed the "Land Girls", could replace men working on farms who had been called up to the military. After the end of the war, Chitty returned to the family home. Her father was made Rector of Yockleton, also in Shropshire, in 1920. During this time she developed her interest in archaeology and particularly in prehistoricartefacts. In 1924, she was appointed the Ordnance Survey'shonorary correspondent for archaeology in Shropshire. In 1926, she also became the local contact for the Ancient Monuments Board. Having met Harold Peake, during 1927 she was tasked with "drawing bronze implements for the British Association". Around this time, she began to create an analytical card index of "national and local archaeological periodicals and other literature"; this would become an important database for professional archaeologists and students. Her artistic training meant that she was asked by Cyril Fox to draw the maps for his book The personality of Britain ; however, these were not acknowledged as her work until the third edition which was published in 1938. In 1938, Chitty's father died and she moved in with her brother, Derwas Chitty, who was the then Rector of Upton, Berkshire. She managed his household until he married fellow archaeologist Mary Kitson Clark in 1943. She then moved by herself, returning to the family's house in Pontesbury, Shropshire. She once more became the local archaeological expert, having been appointed the "Chief Correspondent for Shropshire Ancient Monuments Department". She "drew artefacts, researched and mapped find sites, published reports, and helped to improve local museum collections". She also turned once more to indexing and was asked by the Cambrian Archaeological Association to do so for its Archaeologia Cambrensis. Published in 1964, the index has been described as the "best index for this particular publication". In addition to the indexes she produced, Chitty wrote and published 146 articles in scholarly journals. These were mainly artefact reports on single objects, but she also expanded upon incomplete or incorrect early publications concerning Bronze Agehoards.
Later life
In old age, Chitty retained an interest in archaeology, and attended many of the activities of the learned societies of which she was a member. She developed hypothermia in January 1979, and died on 8 February 1979 at the Hillside Rest Home, Church Stretton, Shropshire. She is buried in the Pontesbury Cemetery in Shropshire.
