Dunlop Tracy's RA successes were when he was living at Kingston Buci, part of Shoreham by Sea, Sussex (1908-12). His work is first mentioned in St Ives in an exhibition review, when his painting, Moonlight upon the Sea, was praised; but as he was then living in Holbrook, Ipswich, his contributions were not regular.

In the 1911 Show Day at St Ives he exhibited three paintings, all of which were seascapes; his works are again mentioned in 1940 and 1945, but it is not certain whether he lived in St Ives during the Second World War or not.

In the parish church at Shoreham, there is a memorial window to his son who died of pneumonia. Tracy is better known as an expert pistol shot and author of a WW1 book on The Service Revolver. He continued to paint between the wars when he moved to the East Coast.
