It's All in a Name

So is it pronounced Gebbie as in Debbie or Geeby as in HeeBeeGeeBee? I came across the road in Taradale on my cycle ride. It is named after Thomas Gebbie who owned land before Taradale land was sold in 1873. His son William J Gebbie was a founding member of the Forresters Lodge in 1886. Until 1903 he was a coach driver on the old Taupo Road. I thought you would all like to know that!
