There is no Emily Augusta BARRETT in 1919. There is an Emily BARRETT, 301 Hereford St, Christchurch, spinster, who doesn't seem to appear on the previous roll nor the following one.
I did notice that in the 1949 electoral roll, William Robert and Emily Augusta are living at 273 Herbert St, Invercargill. He's a drainer, she's listed as married. Also at that address is Leonard William WILKINSON, labourer. There is a corresponding death for a WILKINSON, Leonard William in 1967 aged 46.
