Convict Notes


John McMahon also called himself O’Brien. He was found guilty of stealing a saddle when he was tried at the County Clare Lent Assizes, and sentenced to life imprisonment. The assizes were held in the week from Monday, 8 March to Friday, 12 March 1819. (Dublin Journal, 24 Feb 1819, p.3 re County’s Lent Assize dates). He had a young son also named John who was imprisoned with him, and we'll still find bell From the ship’s indent John McMahon’s details were: Aged: 27 years, Born at Ennis in the Co. Clare. Labourer; Height 5ft 6 &1/4 inches; dark sallow complexion, brown hair, blue eyes. IRISH CRIME Kilkenny Moderator, 20 March 1819, p.4 “ASSIZES INTELLIGENCE, Ennis, March 13 “Yesterday evening the criminal business of our assizes was concluded by passing sentence on the following persons, found guilty of various offences: “ … John McMahon, alias O’Brien, an old offender, for saddle-stealing. To be transported for seven years. John, his son, to be imprisoned, (term not yet recorded) and to find bail.” It appears that he involved his son (must have been quite young) with him in the theft stop being an “old offender” means that he had been tried before the court breakfast. Four other prisoners tried at the same County Clare Assizes as John McMahon were transported on the Minerva, so all were together in gaol as well as being on the convict ship. These were: Pat Coneen (reprieved from being hanged - burglary), Pat Fitzpatrick (reprieved from being hanged – sheep stealing), Michael Clancy (sheep stealing), and Pat Minogue (sheep stealing). in N.S.W: On arrival – John McMahon was on list of convicts disembarked from the 'Minerva' and forwarded to Parramatta for distribution, per Col Sec’s letter dated 30 December 1819. He doesn't appear in any record after this. Did he escape? Did he change his name?
