Looking for Rodwell from Victoria OR Nsw

I'm looking for any information on

Mark Rodwell born in Bombala NSW

Thomas Rodwell (I believe there was 3 generations of Thomas Rodwell's including 1 or 2 that were convicts transported to Van Diemens Land)?

Sarah Baker (Mother of Mark Rodwell)

Ida Stagg (wife of Mark Rodwell)

Douglas Rodwell (son of Mark Rodwell) born in Echuca Vic in 1920

Eileen Durham/Dunham? (wife of Douglas Rodwell)

Any info such as birthdates and places and especially the convict info would be greatly appreciated!
