Thank you so much for your information. It has confirmed that I was following the correct person. It also explains why his family came out in 1849; that is when he received his conditional pardon.
Is there any way of finding out what happened to him when he was released. My guess is that he went to NSW, as that is where his 2 daughters died, Jane (Shields) at Appletree Flat, Mudgee and Mary Ann (Shields) they married brothers.
Thanks.
