Hi
..... just a little more ....
Have just spoken to the Early Settlers Museum at Petone (they're in my "neighbourhood"). Essentially what you see on their online database, is about as much information (I am told), as they have. However, at the Museum itself, they have an inter-active display (on early settlers) which sometimes offers a few more snippets of info - some of which has been contributed by descendants ( and who in a few instances, have left their contact details).
The museum attendant checked a little further - sadly they have no passenger list for the "Indian Queen" ... and although they have a note of the arrival of "James NAIRN", alongside his name is the word "Anon". (So, no further information on him, nor an indication of who supplied the details).
I have also just located the name of another James NAIRN (of Sanson), researcher - am hoping her e-mail addy is still valid ? Will however send you the contact details, via a PM.
