I have probably put this in the wrong place, sorry. Not sure where to find correct board.
I have a Peter Doyle born approx 1803 in Ireland, he was an engineman on his sons marriage cert. I have found him (I think) in the 1841 census married to a Mary in Cleator Moor, Cumberland. It says coal miner, then again on 51 he was an engine driver, but was a widow. So think that was him. I know he married a Mary and she was apparently a quaker, he was Catholic. They came over from Ireland sometime before 1830 as their children were all born in Cumberland.
My question is, how do you find people in Ireland ie marriage and passenger lists, and how would I find out if their religion was right. I have been told that Cleator Moor was called little Ireland and the majority of them were Catholic who came over from Ireland.
Many thanks
