I am looking for information on my ancestor Michael J Doyle. He was born in 1845 in Mayo Ireland. He immigrated to the United States in or around 1861 (Census Records). He was Catholic. He moved to Cleveland Ohio and married Elizabeth Keeley in 1866. They lived on Church street in Cleveland. He was naturalized by 1900. He died in 1906 in Cleveland.
There is another Michael J Doyle who lived in Sandusky Ohio - not far from Cleveland who married an Elizabeth Foyle - This is not the same person, but perhaps cousins.
My questions is - how can I find more information about the Doyles from Mayo Ireland in the 1800's? Doyle is a very popular name and it is hard to determine which one is the right one. I do not know if he had any brothers or sisters, I assume he would because most did at the time. I do not know the Parish he is from? Was there any paperwork or documents that the family would file before leaving Ireland or would they just leave? Any information would be greatly appreciated. Thank you
