Gallantry Lane in Halswell and nothing on library website. The council website just had the name and nothing about the reason for the name. Gallantry means courageous behaviour especially in battle. This street is near Valour Lane and there has to be a connection.
Edited as I have found out the reason for the name of the street. The streets in the subdivision at 340 Halswell Junction Road have been named after the young men who are on the Halswell War Memorial. They all died in World War One.
There are 8 houses here built between 2019 and 2022 and they all seemed to look exactly the same. There wasn’t a footpath
