Mcgrain v Armstrong

K B, Mcgrain v. Armstrong 8.7.1800 / 12.7.1800 Macgray (at Curran's?)
Perhaps John Warneford Armstrong Dict Irish Biog 1770-1858 noted for his active suppression amd harsh treatment of rebels and radicals. The only possibility I could find for Mcgrain/Macgray was Dublin Trades 1797 George Magrane hat manufacturer and merchant. K B was presumably Kings Bench. Sadly I don't have easy access to Dublin newspapers which may have covered this case
