Looking for Rouvray

Hi I am a new member and I have been researching my family tree for around 5 year now. I live in Adelaide, South Australia. I have some friends in the UK that have been helping me with my tree and have been doing a fantastic job.
I am researching, at the moment, a Joseph Rouvray b abt 1770 and still looking for more info on this part of my family.
