If yours is the Thomas Keegan who lived at 54 Newfield Street Tunstall he actually died in the North Staffordshire Infirmary, according to the National Probate Register, which might be why his death isn't listed anywhere as a mining death. He may have been taken ill, rather than suffer an accident. Otherwise I'm sure that his death, like my ggg's lone death would be listed on the North Staffs Miners site. If it was a mining accident, there would have been an inquest which would have been reported in the Staffordshire Sentinel a few days after his death. Good luck, Fran
