Ancestry have just released the Index for the above covering the years 1700-1950. I put in Yorkshire for place of death - there were 7,546 results. The Index gives approx birth year, age, death date, death place, occupation, name of colliery and the owner and notes (cause of death) For those without an Ancestry subscription the same information can be obtained for free from: http://www.cmhrc.co.uk (The Coalmining History Resource Centre) I don't know why but I put in ADEY in the search engine on this site and didn't get a result but put in Thomas ADEY and I did. So worth putting in a first name if you don't get a result. One tragic story concerned Joseph BIRTLEY who was run over by waggons while taking his father's dinner to the works. He was 7 years old.
