Clara M Elliot - Information on Clara's husband Edward Rogers

I am looking for information on Clara Elliott (Rogers) and more specifically Edward Rogers her husband. I believe they were my Grandfather's adopted parents, Horace Rogers (born Elliott/Newbury) his birth mum was Ethel Elliott (Towns). I would love to know how my Pop became a Rogers. There was also a Teddy Rogers jnr and Edward (Teddy Snr) brother was Billy Rogers and they all lived in Cabramatta back in the 1920/30s.

Please message me through here if you have any information, Thanks :)
