Meaning of song lyrics in 'Monto'

PMBC

Wondering the meaning of the first line in the fourth verse of Monto (the version by The Dubliners). It refers to Carey, 'Skin- the goat' and O'Donnell. The words that I first learned years back went 'O'Donnell killed him on the boat' which obviously is incorrect historically.

James Fitzharris nicknamed Skin-the-Goat (4 October 1833 – 7 September 1910) was a member of the Invincibles.

He served as getaway driver during the assassination of Permanent Under SecretaryThomas Henry Burke and Lord Frederick Cavendish in Phoenix Park. He was later tried and found not guilty of the murders but in a retrial in May 1883, was convicted of conspiracy and accessory to murder and sentenced to penal servitude for life. He was released from prison in 1899 and visited the United States until he was deported back to Ireland in 1900.[3]

James Carey (1845–1883) was a Fenian, most notable for his involvement in the Phoenix Park Murders. On 13 February, Carey turned queen's evidence and betrayed the complete details of the Invincibles and of the killers in the Phoenix Park. His evidence – together with that of another informer Michael Kavanagh – resulted in the execution by hanging of five of his associates.
