“That on the application of the owners Messrs Sinclair and Boyd the names of four new streets, on their property situate off Bloomfied avenue hitherto known, as First Street, Second Street, Third Street, Fourth Street: be changed to Avondale Street; Oakdale Street; Elmdale Street; and Ashdale Street respectively.” Minutes, Improvement Committee, 6th April 1898. There is an area in Scotland called Avondale and the village of Avondale in New South Wales. The next street beside Avondale Street is Elmdale Street, there is an Elmdale in Canada. The Belfast And Province Of Ulster Directory 1899 contains references to Avondale Street. Avondale was the name of the birthplace and home of Charles Stewart Parnell (27 June 1846 – 6 October 1891). The difficulty with the suggestion that the street might be called after it is the Unionist opposition to Home Rule which Parnell supported. https://bloomfieldbelfast.co.uk/robert-boyd-1845-1869.php#Boyd02
