Hello Kylie
I have extensive information on Nixons from Castlewarren, Co.Tyrone . Do you have any more information on your Nixons?
The family in question had parents (who remained in Ireland), John and Martha. Their children, with birth years, were Mary Jane 1846, Catherine 1848, James and William 1850 twins, Sarah Anne 1852, John 1853, Thomas 1855, Robert 1857, George 1859 and Matilda 1861. Robert died in 1866, aged 9. I know William stayed in Ireland, and took over the family farm. John also stayed in Ireland, he lived and worked in Derry. I think Thomas and George emigrated around 1888. Matilda may have been known as Martha.
Does this match any of your research?
Kind regards,
Joan Allen.
