A few Kellow families (tin miners and copper miners) from Cornwall (Baldhu and St Cleer areas) emigrated to Australia with their children to work in South Australia mines, or Victoria or Newcastle mines, N.S.W. around the 1870's.
I believe the Cornish mines were failing just as the Australian mines were booming and that Cornish miners played a big part in the way Australian mines developed and operated.
My great grandmother Sophia Kellow (1863) was from St Cleer Cornwall and she arrived in Adelaide South Australia (1880'ish) with some of her brothers and sisters (Joseph and Ann Kellow and ??) although one (William Charles Kellow 1865) went to Victoria and one (John Doney Kellow 1853) went to Newcastle, N.S.W.Her uncle Benjamin Kellow (1809) and his family went to Shepparton Victoria.
I can't find any info on their emigration/immigration - only where they eventually married or appeared on Australian census records.
I have had a lot of help from John Kellow in Victoria who sent me his Australian Kellow tree (which links to but doesn't include my bunch).I can put you in touch with him.
Sophia's father was John Kellow (1821) who was a son of Sampson Kellow and Catherine Michell.I am stuck here as I can't find Sampson's birth or parents.
Any help appreciated. I am happy to share the little I know.
