Hello, I also live in NZ.
My husbands grandmother was Margaret Isabella Elkin who married William Walker in Wellington in 1888.
Our Elkin family went to Omagh about 1770 and lived at Mullenatomagh and Kilbuck.
Robert Elkin born 1798 was the son of David Elkin and Catherine Smith.
1. Lovey (Olivia) Robinson
2. Elizabeth Mcgraw.
William Elkin born 1835 to Robert Elkin and Lovey.
This Elkin family all came to Sandhurst (Bendigo, Aus) in 1855/6, then came to Oakura (Korutown) near New Plymouth in 1864.
William Elkin and his brothers Alexander and Robert were all in the Taranki militia and farmed their land grants.
Robert never married and died at Margaret's farm in Opotiki
Father Robert died at Oakura in 1874 and Elizabeth died in 1884.
After the parents died William and Robert sold up at Oakura and went to Australia. There is an article in Paperspast site in the Taranaki paper of their farewell party.
Alexander was killed in the same battle as Von Tempsky in 1868.
About the same time there was a minister Rev. Elkin in Auckland - no relation to my Elkins.
