if the Thomas born 1840 were the immigrant then he would fit the first son of John Coole (cooyle) + Eleanor Condrey who was baptised the following day - Malew 18401004 - in 1841 census he is a lead miner in Malew (glancasne next to Moaney Moar among a small group of Lead miners) - Elenor would appear to be dead by 1851c as John has a younger wife Esther Cool (?relation) but still a lead miner - Thomas is still with them. (?if Eleanor bur Rushen 18491205 as would fit with children + 2nd mar in 1850)
There are a couple of possibilities for Eleanor - d/o wm condra + ann Bell or d/o Thos Cundrey + elen kermode - my own guess is for the former
In 1851 John gives birth parish as malew but no obvious match (?if illeg)
