O'Grady surname: questions
What does the surname O'Grady mean?
Woulfe gives O'Grady as a form of Ó Gráda, 'descendant of Gráda', and glosses Gráda as 'noble, illustrious'.[1]
Where in Ireland is the O'Grady name from?
Woulfe says the family was first seated in the parish of Killonasoolagh, near the river Fergus, in the south of Co. Clare, and after 1318 near Tomgraney, with lands in Clare and Galway. He says the name 'is now common in Munster and Connacht'. In 1890 O'Grady births were principally in Clare, Limerick, Dublin and Roscommon.[1][6]
Are Grady and O'Grady the same name?
Not always. Woulfe lists Grady under Ó Gráda, but also gives Grady for Ó Griada, 'a corruption in Connacht' of Mag Riada, which is in use in Galway and Mayo and 'sometimes incorrectly anglicised Grady'. He also prints (O'Grady, Grady) in brackets under Ó Greada, 'an old Munster surname', and says Ó Gráda is 'to be distinguished from' it.[1][2][3][4]
Why did some O'Gradys become Brady?
After telling how Sir Donogh O'Grady was knighted in 1543, Woulfe writes that 'the surname about this time, in some unaccountable way, got anglicised O'Brady and Brady'. His son Hugh Brady was the first Protestant bishop of Meath, and another son, John O'Grady, alias Brady, was the ancestor of the O'Gradys of Kilballyowen, Co. Limerick. Woulfe gives the Brady surname itself a separate origin: Mac Brádaigh, 'the name of a great Cavan family'.[1][15]
Who was Viscount Guillamore?
The Dictionary of National Biography says Standish O'Grady (1766–1840), son of Darby O'Grady of Mount Prospect, Limerick, was attorney-general from 1803 and lord chief baron from 1805, and on retiring in 1831 was created Viscount Guillamore of Cahir Guillamore and Baron O'Grady of Rockbarton, co. Limerick.[14]
