Dalgarven Place in Hillsborough and nothing on the library website. Dalgarven in a place in Scotland and I would have driven through it when going to Irvine to visit friends. The valuation website that I use had three houses here with the earliest being built in 1970. That is probably incorrect as Papers Past had ads in 1983 offering three sections for sale. I thought that there was a new house being built here but going by Google maps it has been there for a while. The three houses look different now compared to pre earthquake street view.
Edited to say that on a couple of maps for the subdivision in 1975 this street had the name Arden Place. No other entries for this name and I couldn’t find out why the name change.
