Hi Wee Ann, cannot help you directly but following link seems promising http://79.170.40.163/forestofdeanhistory.org.uk/LHScdrollofhonour.htm

It's all about Mining & Quarry Fatalities in the Forest of Dean & it's on CD, only trouble is it costs £19.99 (ouch!) Click on 'Click here to buy a copy of the CD..........' at bottom of page.

There's no guarantee that Bilson Colliery will be on there, so why not contact them & ask if it is on the CD before thinking of buying. Good luck & let us know what happens. Regards, TonyR.
