Hi Gemini
My Thomas Hanning (my g-grandfather) arrived in New Zealand from Rostellan, co Cork, Ireland in 1861. He may have travelled to New Zealand on a ship that sailed from Glasgow, but he was Irish to the core.
Apart from early carting to the gold diggings, he was a farmer and never in the hotel business as far as I know.
There was a scottish family of Hannings (Robert Hanning et al) who settled in the Catlins area of Southland, but they had no Thomas that I am aware of.
Sorry I cant help further,
Terry
