George Charles Bennett of the Pinery South Australia

George Charles BENNETT born c1841 married Sarah Egan FEATHERSTONE in
1873 in Port Adelaide, South Australia. George and Sarah had 4
children and Sarah died in 1880. George remarried to Lucy COLLINS (nee
MINEAR) and George and Lucy had 6 children in The Pinery, South
Australia.

I am trying to find where George Charles BENNETT was born and some
information about his family. His father is Thomas BENNETT, but I
don't know George's mother's name.

Can anyone help fill in some of the gaps?
