Wicker Family from Victoria Australia

Hello. My name is Royce Baucke - I am from New Zealand but now living in Qld. Australia.
I am looking and keen to meet descendants of Ann Elzabeth Hills who married Henry James Wicker (both convicts).
My Grand mother's name is Hilda Maud Wicker daughter of Thomas Wicker and Alice Morgan.
I would love to make a connection with any living family members of the Wicker family.
Best wishes - and thankyou.
Royce Baucke.
