“That on the application of the owners, the Martin Estates Company Ltd, two new streets on their property situate off Donegall Road be named Kitchener Street and Loudan Street and three new streets on their property, situate off Agincourt Avenue, Collingwood Avenue, Cadogan Street and Curzon Street. (12th October 1898).”
Curzon Street is listed in The Belfast And Province Of Ulster Directory 1899 with the additional description indicating the left hand side of the street was still being built.
It is likely the street was named after George Curzon, 1st Marquess Curzon of Kedleston. His maiden speech in the House of Commons in 1886 was mostly an attack on Home Rule and Irish Nationalism.
