Hi Sue,
It is very confusing isn't it. Elinor would be with Thomas in 1841 is this right? I can check on Ancestry. For your information Robert Corkill was a miner and was so given in Penninghame in 1851 and also on death cert. The certificate also said his father was a miner or mariner it was very unclear but I think miner is more likely. I have been trying to find Robert in 1841 but not having much luck. Are there any specific places for mining on IOM?
