I wondered if someone could help me....
I have a James Thomas Mernagh born c1846 County Mayo - information from the English census's.
First appears on the 1881 English census.
He marries in Rathdown 1868 to Birmingham born Charlotte Bowley, (I found this info off mayoancestors.com)
How do I find James's family without travelling to Ireland?
Can I apply for his marriage certificate? If so where do I apply? Are there any census information for Ireland pre 1881, or are there Electoral Registers or land registers?
I really have no idea how to go any further back, I have read some of the information available on this site, but they don't seem to answer any of my questions.
I would really appreciate some step by step answers

Thanks Angi x
