“That on the application of the owner Mr James McCaughey a new street on his property situate off Cliftonville Road be named Lower Easton Street”. (Improvement Committee, 20th July 1892). Lower Easton Street as a name is no longer used.
“That on the application of the owner, Mr James McCaughey a new street on his property, situate off Cliftonville, be named Easton Crescent". (29th November 1893).
There was an advertisement for the sale of property in the Belfast News-Letter on Friday 26 September 1884 for "Cliftonville Property, known as Easton Lodge". Easton Lodge also features on the Ordnance Survey map (1838 - 1862).
This would seem to indicate the "Easton streets" take their name from Easton Lodge.
