I am looking for details on Mr Joseph THOMAS (maybe known as Jac) of Grange, Co Kildare. He married Sarah FRANKFORT (unusual name for that part of the world). A child Elizabeth Thomas (c1835/40 - 1914) was born to them at Grange (could this be Grangerosnolvan

). Elizabeth, aged 21 years, emigrated to Australia. She left Plymouth on the 5 March 1860 and sailed on the “Atalanta” a journey of 86 days, arriving in Melbourne on 30 May 1860.
Joseph and Sarah Thomas died in Ireland. I do know that Joseph Thomas was a carpenter, but no details as to place of birth or death.
Does anyone have any thoughts?
