Having read your article about the Oaks Colliery Explosion I can add 3 names to your list:
George Ellis (19)
Tom Donkin (25)
George Wilkinson (18)
And William Henry Banks Who was killed at Wombwell Main Colliery, Sept 29th 1865, aged 22
I have attached photographs of their headstones, which are all located in Christ Church Graveyard, Doncaster Road, Stairfoot, Barnsley. This is not intended to be a comprehensive list and other graves may be present in this graveyard. The graveyard also contains a memorial to those killed on the explosion, for which I have also added a photograph.
I am also sure you will be aware of the monument to rescue workers responding to the original explosion, who died in a subsequent explosion which occurred 13 December 1866. I have also added a photograph of this memorial.
