Looking for Confirmation of the William Greetham and Susanna Would Heirachy

Hi Fellow Researchers
My research is to establish and confirm my UK heritage.
My fathers father was a TAYLOR of the TAYLOR/GREETHAM line - George TAYLOR // Elizabeth GREETHAM
George Greetham TAYLOR // Joseph Swan TAYLOR // Clarence Greetham TAYLOR //
This also takes in a KIDD as well as SWAN, GARRETT and TAME
*** I am already aware that the father of Elizabeth Greetham is William Greetham who's sister is Elizabeth Greetham,
who marries Thomas Copping and goes to CANADA.

My fathers mother side are EASTON from Edinburgh, Scotland not the real part of Scotland (so they tell me)
David Reid EASTON // David EASTON // William Fowler EASTON // William Fowler EASTON [2]

All these names end up in Melbourne, Australia throughout the 1850's to 1880's

Cheers and regards
