Hi all,
I have just joined ancestry and found your messages. In relation to lancelot Iredale, the convict, he died at Surry Hills, NSW on 16 June 1848. He was married twice - Sarah Young (in UK - 3 daughters) then Kezia Bedford (NSW - 10 children). I have quite a bit of information on Lancelot. There is a painting of him and Kezia on the Picture Australia website.
