My friend Pat lived in Capilano Road, Perry Common and that was the first Capilano name I had come across. The second Capilano name I am familiar with is in North Vancouver, Canada, If you Google Capilano you will find many references to it as it is associated with the Squamish Indian Band who have lived on these lands for centuries. There is a Capilano University, Golf Club and the famous Capilano Suspension Bridge.
I found this description of the name Capilano online. It is on the Capilano Honey Co site.
The name "Capilano" has a nostalgic connection. It means `rushing water' in the language of the Native Indian tribe, the Squamish, who occupied the Capilano District in North Vancouver, BC, Canada.
It was here that company founder Tim Smith met his wife, Jill, while stationed in Canada as a RAAF flying instructor in World War II.
I know we are still nowhere nearer to finding out why a street in Perry Common was named as such. Have to do a bit more digging.
