Hi Graeme!
Ah then it would be your Uncle John I had written to.
I am in the US actually, by way of Canada. I am both Jubb and Kerr. There were three Kerr brothers who arrived in Halifax from Scotland: John Bell Kerr, Robert, and William.
Tom Jubb married John Bell's daughter Janet, and they had Lily Hannah. Then Janet died.
Then Tom married Robert's daughter Annie, and they had my grandfather. So I am descended from Robert Kerr.
William set off for NZ in 1858 and his wife Ann Morley's family joined them on the next sailing. I think the ship was the Blue Jacket?
I would dearly love to see a scan of the ticket, what an heirloom that would be! I guess the family was right in the middle of the Maori wars.
