Following is all info I have on George Carlyle -
Left Melbourne on 23/01/1863 on the 'Saint Clair' arriving in Port Chalmers, Otago, NZ.
1867-1869, lived in Naesby-Manuherikia District electoral role.
1870 - livedin Naesby, Mount Ida electorate
1871-1873, lived in Kyeburn, Mount Ida eletorate.
1874 - lived in Maerewhenua, Mount Ida electorate.
So, he arrived in NZ 1863. Son George jnr was born in Geraldine in 1864, therefore it is possible Geo snr married Eliza Smith in Australia. There is no record of their marriage in NZ.
The last record of him is the 1874 electorate record. No death cert found. So maybe he left Eliza and went back to Aust or Scotland. Eliza had to stay in NZ to bring up Geo jnr.
It's trying to match up Geo snr to where he was born in Scotland that we are after, I think the posting by Gadget was looking very good.
