Hi Sandie , Daniel is shown on the IGI as Dani Quayle McKnight , ch 12/8/1819. He had at least siblings 1802 Mary Ann , 1806 John 1810 Eleanor 1812 William Thomas 1816 Charles and 1822 Thomas. A few of the kids are shown as McKnight. ?? The parents appear to have married 29/5/1802 , so it does not make sense.
Edmund Quayle appears to have been buried Andreas 2/2/1848 aged 73.
Jane is shown ch 5/7/1835 Lezayre , she is shown as Jane Gill or Kelley as father is John Gill or Kelley , mother is Margaret Cowin , on 1841 census Jane is shown as 5 , father 45 mother 30.
I am sure that Jane's parents also came to Melbourne , on the list , the ages are close.

Cheers
David Dwyer
