"That on the application of Mr R A Macrory, a new street off Duncairn Gardens be named Ilchester Street and a new street from Edlingham Street to Hallidays Road Upper Mervue Street and that Mr Macrory be requested to submit arnother name in lieu of Hans Street". (21st August 1889).
The Northern Whig on 5th July 1881 contained details of a Statutory note to Creditors following the death of Adam John Macrory "who died at Duncairn aforesaid, on the 28th day of March, 1881, and probate of whose will was granted to Edmund Macrory of Ilchester Gardens, in the County of Middlesex, Barrister-at-Law".
An earlier notice in the Belfast Newsletter on Monday, January 12, 1852 gave details of Edmund Macrory, Esq. A.B., T.C.D., second son of Adam John Macrory, of Duncairn, in the county of Antrim, Esq. offering himself to be called to the bar.
It would seem that the name Ilchester Street comes from Edmund Macrory's address in Middlesex.
