Hello Anne Warm Hole Pit sounds a bit like a collier's nickname for a pit, doesn't it? Kearsley area was littered with small pits in the old days. I had a quick browse at the 1849 map but couldn't see anything similar. One way to find out more detail is to get info from Ian Winstanley's Mining Deaths Database (it will cost you!). There is an entry for a J. Platt in the 1850-59 period, but it could be anywhere in Britain. You could always email him with what you know and he ought to confirm first whether it is the person you are interested in. Tyldesley is not all that far from Kearsley (~5 miles), but I'd have thought in the 1850s the distance would have been too far for a daily trek to work and back when there where plenty of nearer pits. I've never heard of Goor, but I'm not from Tyldesley. I don't have access to that census, but if you'd like to email the page it to me, I'll see what I can make of it if you like. Regards Peter Wood
