I am trying to obtain photos or newspaper reports of a wedding that
took place in Holland,  I think on 16 February 2002 in
Haastrecht/Oudewater area between Ernst Boekhorst and Jorien Schuit.
The wedding dress had a train of 776 metres and currently holds the
world record.
I have spoken to Guinness world records who say that now the record
has been confirmed, all material has beenreturned to the record holder
so they have nothing and they are not terribly helpful
Any info published in local papers or photos anywhere would be
appreciated
many thanks

I am not sure whether this helps, but if you are looking for the
longest wedding dress, you should look for another one.
I am collecting information about unusual world records, and I am the
maintainer of http://www.recordholders.org.
I am pretty sure that there was a longer wedding dress somewhen in the
80's used for a wedding in Germany. If I remember right, it was more
than 1000 m long, and I am sure that I will find a photo of it in my
archives. This wedding dress was never published in the Guinness Book
of Records, which started the category later with lengths about 100 m
"only".
Unfortunately, as I am not an "official Google Answers Researcher", I
cannot contact you to send the picture, and for copyright reasons, I
cannot upload it on the web.
