Sir William Cusack-Smith, 2nd Baronet FRS (23 January 1766 – 21 August 1836) was an Irish baronet, politician, and judge.

Background and education

Cusack-Smith was the only surviving son of Sir Michael Smith, 1st Baronet, Master of the Rolls in Ireland from 1801 to 1806, and his first wife Maryanne Cusack, daughter of James Cusack of Ballyronan, County Wicklow. He was educated at Eton and Christ Church, Oxford.

Legal and judicial career

Cusack-Smith was called to the Irish Bar in 1788, having studied at Lincoln's Inn, became King's Counsel in 1795, and was made Solicitor-General for Ireland in 1800. He was appointed a Baron of the Exchequer in 1801 at the remarkably early age of 35. The appointment caused some adverse comments, both because of his youth and because he was already displaying signs of eccentricity.[1] In April 1805 he was elected a Fellow of the Royal Society.[2]

He was an eccentric judge who offended Daniel O'Connell. O'Connell raised a motion, carried by MPs on 13 February 1834, to appoint a select committee to enquire into the conduct of Lord Smith in respect of his neglect of duty as a judge, and the introduction of political topics in his charges to grand juries. On the count of neglect, Cusack-Smith had been accused of rarely beginning his court sessions until after noon, occasionally running them until late into the night.[1]The accusation of introducing political topics stemmed from statements made from the bench to grand juries condemning partisan agitation practices, which were themselves perceived as inflammatory due to their one-sided nature, although in fairness he was far from being the only judge to behave in this manner.[1]On 21 February there was an important debate on the matter, and the resolution to appoint the committee was rescinded by a majority of six.

Cusack-Smith, though a devout member of the Church of Ireland, was a lifelong supporter of Catholic Emancipation (his mother was a Roman Catholic),[3] but moved from early rejection of the Act of Union to supporting it. Despite this reversal, his conscientious conduct as a judge was well thought of to the extent that he was even congratulated by voices among the Repealers movement on his escape from parliamentary inquiry.[4]

Cusack-Smith represented Lanesborough in the Irish House of Commons from 1794 to 1798. Subsequently, he sat for Donegal Borough until the Act of Union in 1801.

He was ill for some months before his death, but had appeared to recover. His death, at the family seat in Newtown, was sudden, and was generally believed to be suicide.


William Cusack-Smith added his mother's surname to his own upon her death. He married Hester Fleetwood Berry (29 Jan 1762 – 4 Jun 1832), daughter of Thomas Berry of Eglish Castle, County Offaly and his wife and cousin Frances. They had four children:

Many of Hester's letters to members of her family, particularly her favourite brother Robert, survive.
