It is likely these streets take their name from a residence "Clonaver" off the Holywood Road. The 1858-1859 BPUD Directory listed: “Jas Girdwood, carpet, damask, & room paper warehouse; residence, Clonaver, Sydenham".The assistant city surveyor submitted Memorial signed by owners of houses in Clonaver Crescent requesting that with a view to avoiding confusion that thoroughfare be divided and renamed Clonaver Crescent North and Clonaver Crescent South. The assistant city surveyor intimated that the city surveyor was of the opinion that change would be in the public interest, resolved at the request of the memorialists be acceded to.
