Mary FitzMaurice, 4th Countess of Orkney
Mary FitzMaurice, 4th Countess of Orkney (born Lady Mary O'Brien , born September 4, 1755 , † December 30, 1831 in Beaconsfield , Buckinghamshire ), was a British noblewoman .
Life
She was the only child of Murrough O'Brien, 1st Marquess of Thomond (1726-1808), and Mary O'Brien, 3rd Countess of Orkney (around 1721-1791).
On December 21, 1777 she married the Hon. Thomas FitzMaurice, the younger son of John Petty, 1st Earl of Shelburne (1706–1761). With him she had a son:
- John FitzMaurice, Viscount Kirkwall (1778-1820)
When her mother died in 1791, she inherited her Scottish nobility titles as 4th Countess of Orkney , 4th Viscountess of Kirkwall and 4th Lady Dechmont . Her father's Irish titles were only inheritable in the male line and therefore fell to her cousin William O'Brien, 1st Baron Tadcaster , as 2nd Marquess of Thomond on his death in 1791 .
Since she survived her son, her title of nobility fell on her death in 1831 to his eldest son Thomas FitzMaurice (1803–1877) as the 5th Earl of Orkney.
