Err
How many chaps named William HALL were around in the 1810s and 1820s .... lots
William HALL, came free per Anne Feb 1810, a Missionary, came with his wife. Noticing ship of arrival includes the word "Anne"
Oct 1814 muster, William Hall, per Anne 2, came free, missionary, mustering at Parramatta, off stores
Sept 1825, William Hall, per Ann 1810, Landholder, Sydney.
1828 Census
William Hall, 50 Protestant, at Melville and Cooke (so JM notes this is in the area west of Blacktown towards Emu Plains/Penrith) He owns the land, 2 horses, 161 cattle, and he is a School Master. His wife is Dina HALL aged 50, who came free per Anne 1810.
With them are their children. ..... You need to be good with mental Arthurmagictrickerals here ....
Dina Hall, aged 13 (1828-13 = 1815, remember her mum and her dad arrived 1810) arrived per Vansittart, came free, protestant, daughter of William Hall,
Henry Hall, aged 9, protestant, arrived per Boddington 1824, son of William Hall arrived per Boddington 1824
John Hall, aged 7 protestant, arrived per Boddington 1824, came free, son of William Hall
The above family is obviously NOT your Sarah HALL but I am including them (there are other families too,) as they are in the 1828 census as a family group and there's something wrong in the chronology data.
