Looking for the Cox Family of Kensington Wiee Kent England

I am trying to trace the acestary of hennry cox born 04/04/1842. Henry married Harriet Conley on 28/05/1871. Harriet was born at Bradbourne, Kent, on 05/01/1847.

Henry's son Harry is my Great Grandfather. He was born in Kent England at Faversham in 1872. He Married Mary Elizabeth Trebilcock who was born in 1878. Henry died in the 1950's and Mary died in 1932. Both at Ulverstone in tasmania, Australia
