Hampson of Leeds Kent England

I am looking for John & Elizabeth Hampson (nee Exley?), he was born in 1855 in Wharfdale, England. I have them coming out to Australia in 1900 to build the railway. They returned to England with their children, Henry and Flossie?, they left my great grandmother behind Louisa Edwina Hampson, born 2nd Oct 1880 in Leeds, Kent. She stayed and married my great grandfather William Stephen Robinson born in 1879 in New Zealand (of British Descent). There are very few records of Louisa in Britain and I can't locate the records for John & Elizabeth returning to England. Is there anyone out there that knows the family tree?
