Where to find Ireland birth/census info for great grandparents (circa 1850)?
I'm looking for info for Ellen Donnelly Donahue (about 1848) and Owen Patrick Donahue (about 1846). I think Ellen came to the US in 1850 and Owen arrived around 1870. I believe one or both was possibly from North Leinster, Connacht, Galway or Mayo. I'd like to find their parents. They had children, Hugh, Edward, Owen, Anna, Catherine, Mary and John and possibly others. They were in Maryland recently after arrival and for the birth of Hugh, then moved to Northern Ky where the other children were born.
Any help or guidance in locating their parents or Ellen and Patrick's birth or other records would be appreciated.
