Looking for John Harwood

I'm looking for info on my my great grand parent John Harwood.

He was born abt. 1843 in England.

He was married to Kate Harwood, she died in 1874.

He married my great grand mother Isabella McAloon on 17th March 1875 at St. Francis Catholic Church, Melbourne, Australia.

She was born in Dunoon, Scotland 1876.

He died in 1888 in Prahran, Victoria, Australia.

I would like to know more about his life and family back in England, hope you can help, cheers Rick Silverwood.
