Standish O'Grady, 1st Viscount Guillamore

[2] He inherited the Cahir Guillamore estate on the death of his uncle John and was appointed High Sheriff of County Limerick for 1790.

[3] On 10 June 1803, after the murder of Lord Kilwarden, O'Grady became Attorney-General and was sworn of the Privy Council of Ireland.

He was a sound judge, and David Richard Pigot, his successor as Chief Baron of the Irish Exchequer, expressed the opinion: "O'Grady was the ablest man whose mind I ever saw at work".

[6] He clashed with his superiors in 1816 when they brought quo warranto proceedings to challenge his right to appoint his son Waller as a Court clerk.

[6] In 1790 O'Grady married Katharine (died 1853), second daughter of John Thomas Waller of Castletown, co.
