The information you posted many months ago certainly contains some of my ancestors though I didn't know that at the time. My gg grandfather was George Cormack from Caithness who travelled to NZ on the " Invercargill " from Glasgow in 1875.In 1880 he married Grace Mackie in Palmerston.One of the witnesses to the marriage was William Cormack a Railway Foreman from Caversham Dunedin. I havent established what link William is to George yet. According to George's death Certificate his parents were John Cormack and Ann Sutherland who were married in Latheron Caithness. Obviously there is some family link to your line but I haven't worked it out yet. Dianne Cormack.
