Looking for information about my GGGrandfather, James Cumming. He was listed on the 1841 & 1851 census for East Kilbride, Lanark, Scotland as an "iron stone miner" B. 1812 in Ireland. I can't find him on the 1861 census. Three of his sons were on the 1861 census for Old Monkland listed as "coal miner". Marriage records of children in 1863 for Lanark list James as deceased. He is not on the General Index of Deaths of Scotland (1855-63). I wonder if anyone knows if there were any mine disasters between 1851 to 1855 in Lanark. I am also searching for information on any Cumming/s and Crilly families from Blantyre who were miners in the same period. John Cummings
