Hey Jamjar,
John was born in Bourke about 1873 (I gleaned this from the transcript - it states he was 32 when they married in 1905) although his birth is proving somewhat hard to find. Sophie was born in Hay about 1871 (again from the transcipt). They married in Sydney 1905. They were the witnesses at my grandparents (Sydney Norton & Ada Henry) marriage in 1909.
From what I can gather the boys in the family were pretty close as they lived within cooee of each other (eastern suburbs of Sydney) for many years. In the 1903 census they were all around the same address.
I only got on to this when I was looking at my grandparents wedding (the original from 1909) certificate and saw their signatures - that's one reason I ordered theirs at the same time. Ada is proving very elusive but that's another story.
That's about all I had up until yesterday when I received the transcript of John and Sophie's marriage and today when I had the extremely

good idea of posting here on Rootschat.
The more I can find out the better!!!
Cheers,
Julie
