Griselinia Crescent in Wigram and too new for library website. It is probably named after a plant. I did check ancestry website as I was expecting it to be named after a member of the Dellaca family. As I started writing this I decided to have another google and found information on the council website – Griselinia is a genus of seven species of shrubs and trees, with a highly disjunct distribution native to New Zealand and South America. It is a classic example of the Antarctic flora. It is a broadleaf, named for Franseco Griselini, an Italian naturalist from the 1700s.
This street is on maps but it hasn’t been developed or formed yet. The developers map on the council website was interesting as it was showing several houses on a section where I know that there is only one house.
