Hi Linda, It has been a while since you posted this message and I am hoping you still have the same contacts.
Anyway I am kind of linked (mainly through marriage) to the Robinson family that you are talking about in this and other related messages.
In doing the Brown family (where Harena Robinson, dau, Joseph Robinson and Kauamo (or variant of her name)married William Brown a ggg uncle) I have come across the rest of the family which I have found interesting and have been digging into it more. I have some notes from the National library as well.
Would love to make contact
Claire
