Gahagan (Goaghan, Goghan, Geoghegan, Gaughan) documented as being born in County Roscommon, Ireland in the 1861 England Census Records
The early years of the England Census records infrequently report the County of birth in Ireland, but notation of more than just the country becomes more frequent from the 1861 census on.
I have yet to identify any records in a general search for Gahagans or any its variations born in County Roscommon.
Regarding Surname Gahagan: There were many individuals with the Gahagan surname who were listed as being born in Ireland (undocumented county) with the highest numbers being in Lancashire County and lesser numbers in Middlesex, Yorkshire, Warwickshire, Staffordshire, Cheshire, Hampshire, Durham and Essex.
