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".Resolved that the names Clonaver Crescent and Clonaver Drive be approved for New Streets of Circular Route on the property of Mr R. McMullan. (10th August 1937).
