“That Messrs J. Fraser & Son on behalf of Mrs. Henderson be informed the Committee will recommend the Council to sanction the name of Duke Street for a new street off Newtownards Road, but suggest other names instead of Killaire Street and Florence Street should be submitted as it is thought inconvenience might accrue there being names similar to those already in the town". (22 September 1886)
The author surmises the street may have been called after the Duke of Abercorn who served as Lord Lieutenant for Ireland for several years and who died on 31 October 1885.
