Both my grandfather Wilfred JACKLIN 1896-1967 and great grandfather Daniel JACKLIN 1862-1953 worked the South Yorkshire coalfield. I am still trying to ascertain at which colliery or collieries they were employed, and for how long. There were several collieries in this area though transport would be an issue so presumably they would have worked reasonably close to home. This map courtesy of the Coal Mining Resource Centre details the South Yorkshire coalfield. Daniel JACKLIN (JACKLEN) aged 18 years appears on the England and Wales Census 1881, living and working as a labourer for Richard EARNSHAW on a farm of 62 acres at Crayke, North Yorkshire. By the time of the England and Wales Census 1891, Daniel (now age 28 years) has moved south to Bradley Yard, Aston-cum-Aughton, Rotherham, West Riding of Yorkshire, married Ziller ALLEN 1858-1949 at the Church of All Saints, Aston-cum-Aughton, and is now working as a coal miner.
