Henry Deane Grady of Stillorgan Castle/Mount Eagle House.
Henry Deane Grady of Stillorgan Castle was the son of Standish O’Grady and Elizabeth Deane and was
called to the bar in 1787. He married Dorcas, the daughter of William Spread, lawyer, of Ballycannon,
Co Cork and Elizabeth Peard. He was a successful barrister and entered the Irish parliament for his
native Limerick in 1797.
A small man, he was known for his wit, humour and eloquence, it was said that his wink said as much
as many a rival's speech. He was also quite the duellist having taken part in at least four. He succeeded
to Lodge in Co Limerick on the death of his father in 1809. They were living at York Street in 1799 when
one of their children was born but by 1809 they were living in Stillorgan.
He was Counsel to Excise and Customs for over 20 years and when he retired he received a pension of two
thousand a year. His obit mentions him as the father-in-law of Lord Muskerry, Lord Massareene, Lord E
Chichester, Sir David Roche & the late Mr Blennerhassett and during his tenure of Stillorgan castle, it seems
that the house became known as the House of Lords due to the illustrious marriages of his daughters.
