Looking for Redpath Family Nsw and South Australia

I am trying to find the family story behind John Redpath and Janet(Jessie)Redpath nee Andrews. I am not sure of birthdates, but they married in Grafton in 1872 and had 6 children, born in Richmond River, Redfern and Port Stephens. They seemed to move around a fair bit and I am interested to know their story.

In 1873-1874 they moved from Richmond River to Redfern

1880 they moved North to Port Stephens

1882 they were back in Redfern.

One of the children, Anne Jane may have ended up in South Australia.

Any help would be most welcome.
