Also on
www.familysearch.org i found
Richard Joseph Creagh born 5th May 1867 son of Michael Creagh and Ellen Callaghan
William Creagh born 27 Apr 1873 son of Michael Creagh and Ellen Callaghan
Ellen Creagh born 23 Feb 1876 daughter of Michael Creagh and Ellen Callaghan
Mary Elizabeth Creagh born 16 Oct 1864 daughter of Michael Creagh and Ellen Callaghan
All this was in Mallow Registration District Cork which covers Doneraile area.
I have found the death of a Richard Creagh in Oct-Dec 1916 Mallow Registration District aged 50.
Now the only Richard born around that time (1866-1867) is your Richard. And only Richard in the Census that fits is your Richard so maybe he returned and died in Cork in 1916.
