Thanks Looby,
Robert LATTA would have been 58 and Janet (Jean) LATTA (nee LINDSAY) would have been 59 (Still not sure if these dates are correct).
The 1851 census in Kilmarnock listed 42 Glencarn Street as Robert 44, Janet 42, Agnes 21, Robert 9, William 7 and David 5.
Robert and Janet married in Kilmarnock, Ayrshire in 1829. Robert and Janet both died in Sydney Australia, Robert in 1882 age 85 years and Janet in 1896
I am actually looking for a connection between my Robert LATTA 1805-1882 and Robert LATTA 1816-1874, as I mentioned before they resided in the same address on arrival into Australia.
Thanks and regards - Leon LATTA
