Arthur Cunningham, KC, opened his law office at 79 Clarence Street in 1894, and practised in Kingston until 1931. He was a well known counsel, as well as a respected solicitor. His sons, Douglas (Ben) Cunningham, QC, LLD, and Willis Cunningham, QC continued the law practice, and were later joined by Robert Little, QC, the Honourable Douglas Cunningham, QC, the Honourable Peter Milliken, MP and David Bonham, QC, FCA.
