Hi again,
I would not take info on Trees as completely correct.
EG's
One has William/Mary Ann as having a Daug Susannah 1839 in South Australia
Another has them leaving England 1849.
So not possible!
If they left 1849 for Australia this may be the 1841 Census for them;
1841 Census
Calstock, Cornwall
HO107/133/2/Calstock
William HALLS, 30, Copper Miner
Mary, 30
James, 15
William, 12
John, 8
Grace, 7
Mary Ann, 4
Susanah, 2
Marriage;
02 December 1823, St Noona, Alturnun, Cornwall
William HALES
Mary Ann COUMBE, Minor
Witnesses, Thomas COUMBE/William WADGE
So Mary was underage, ie under 21 at time of Marriage
Marya Ann Hals Death is reg 1888 South Australia aged 88.
Do you have the Cert?
Does it have Parents names/marriage date/arrival in Australia etc?
Also Trees have them arriving 1849 in Sth Australia;
That is this Family which I dont think is yours;
Halls William, 35, Agr. Labourer, 653/1, Birth place Essex ?
Mary A. , 33
Sarah, 14
Eliza, 2
Rosanna, inf
