On 7 August 2012 the Defense Forces Ireland and the National Archives of Ireland released digitized witness statements from over one thousand people who participated in the revolutionary period from 1913-1921. They were recorded by the Bureau of Military History from 1947-1957.
The Buggy name is mentioned in these witness statements a number of times:
Sean Glancy from Co. Leitrim was a member of the Irish Volunteers and the North Roscommon brigade. After an ambush at Keadue, Roscommon, Glancy and a number of other men were arrested. They were eventually taken to the military barracks in Boyle, Roscommon.
There the Military Provost, Sergeant Buggy, is alleged to have assaulted the men a number times including kicking them down steps and hitting them with his revolver. After a while in their cells the men discovered they could open the doors. However, Buggy heard noise one night and put padlocks on their cell doors.
Harry Phibbs was interviewed about Irish National Clubs in the first decade of the twentieth century. One that he talks about was The Confederate Club. This was an athletic and social club that had a nationalist outlook. He outlines that a man named Buggy [no first name given] was a member, along with former President of Ireland, Sean T. O’Kelly.
