Thomas Magee Ireland to Melbourne Via Fremantle

I am looking for some information about Thomas Magee and his family. According to my mum, an ancestor who I think was Hester Euctace Magee played with the aboriginal children whilst they lived in Perth, Australia. Thomas was a warden at the Fremantle jail.
Specifically, I am looking for someone who is also related to confirm Thomas & Jane Knollin's ancestors and wondered if anyone else had heard this story.
