Hello, i wonder if anyone can help

I have some information about my 2x great grandfather and was wondering if there is anyway to find out more about it

John Keene Smith (could be just Keen(e)) or a variety of spelling of Keensmith.
He changed his name legally to John Keene Smith would there be a record of this anywhere?
Born 3 dec 1847, becam a miner and his life services was in Trades Unions and Politics. He was always in office in the Yorkshire Miners Association and was one of its Pioneers along with Benjamin Pickard and Edward Cowey. He died in an accident age 50 and was buried at Darfield. His large funeral was honoured with the presence of masters and men by local and general officials of the Yorkshire Miners Association, the Miners permanent relief and other societies.
This info has been passed down to me but i am unsure if the is anything worth pursuing or if it is just genral info.
Thanks any help appreciated
