Just looked on the new Ancestry one for a relative who was on the original cmhrc site. The record is not there now on Ancestry
Same with my relatives, although, as a test, I did do some searches for time periods without names and quite a long list came up. Not sure which areas are covered - I noticed that there were some from the Wrexham area but not for the adjacent pits in the Shropshire coalfield
