Hanley Research

If I can't find the connection between the McGinty's in the US and Ireland, I'll go through the Hanley's. Does anyone have any info on the Hanley line from Ireland, probably the Roscommon area? My ggggrandmother was Mary Hanley, b. abt 1815, married Patrick McGinty (shown in census records as McInty probably a writing error)and immigrated to the US in 1847.
