Sub-Constables Ambrose Moriarty and Philip Maguire were acknowledged for the "arrest and conviction of a sheep stealer" in April, 1870. This is in Parliamentary Papers, Accounts and Papers, Law and Crime; Police; Law and Crime (Ireland) 23 October 1884--14 August 1885. Vol. LXIV. For those who haven't seen this title (in Google Books), it includes "Favourable Records" received by members of the RIC between 1870-75 and 1880-85. Fascinating reading. Other volumes are also available.
Then, on 29 May 1870, Ambrose Moriarty and Owen Smyth ("plain clothes police officers") were injured in a rock-trowing incident between Protestants and Catholics that occurred on Rathfriland Road, Newry. Twelve men were arrested for complicity in the disturbance and tried. In a newspaper account of the trial dated 4 July 1870, Dr. Robert Johnston testified that Ambrose lost his right eye, and Smyth suffered a fractured skull. The Belfast News Letter for 26 July 1870 reported that seven defendants (charges against the other five were dropped, apparently) were acquitted. Ambrose's injury ended his RIC career, and he was pensioned.
In 1879, Ambrose was "a collector of tolls at the fowl market in Newry" when Thomas Magrath "without any provocation attack[ed] Mr. Moriarty a violent blow on the head." Magrath was fined £1 or a month in jail. He went to jail.
Magrath was one of the original twelve men charged in the rock-throwing incident in 9 years earlier against whom charges were dropped.
Ambrose died in 1887 at age 49. I don't yet know the cause of death. The following year, his widow and their five children (including my Grandmother) emigrated to Chicago.
