Hi Loz   

Yes, those are the articles I found earlier and I'm pretty sure that Edgar HYDE is part of 
this particular HYDE/COULDREY clan who were in the Wairoa South/Clevedon area.   (And that school record for Edgar shows that in the 1880's, he was at Clevedon school).
Thomas HYDE and George COULDREY also ran a boat/ferry service (before they had the store - or it may have been part of that business ?).      
The Thomas HYDE referred to, is listed on the IGI with a (first wife) named Sarah COULDREY ??     (They had one son -William ? from memory - and 
he was not the father of Edgar - so there has to be some other Hyde/Couldrey connection?)
And somewhere I read also, that this Thomas had previously been in Adelaide, which makes me wonder if that might be where the COULDREY link comes from ?
Gawd ... sorting out these other "related" families though, is a bit complicated !    

I think it might be a good idea, to get Edgar HYDE's 1876 birth cert. ?      Especially to confirm his mother's maiden name.
I'll take another look at these articles.
