Looking for Thomas Robinson Married Emma Ward IN Port Macquarie

According to our records Thomas was born in London in 1843. He came to Australia and married Emma WARD in Port Macquarie NSW on 19th October 1870. He then became a pilot's boatman until he retired, and died in Sydney on 15th July 1909. He was also the lighthouse keeper at Tacking Point, Port Macquarie.

We would like to know about his parents and any siblings. All that is on the certificate we have is his father as James, who is listed as a butcher, and his mother as May (name unknown).
