THE CHIEF SECRETARY'S LODGE, Phoenix Park, Dublin, was surrounded by 62 acres of parkland and was completed in 1776.
It was purchased by HM Government in 1782 and became the official residence of the Chief Secretary until 1922, when it became US Ambassador's residence.
I have written an article about the Chief Secretary's Lodge here.
PORTLEMAN HOUSE (or Port Loman), near Mullingar, County Westmeath, former residence of the 1st Baron de Blaquiere, was an 18th century house of three storeys and six bays.
It was built on rising ground above Lough Owel. The grounds comprised eight acres.
The main entrance was in a pillared recess; elaborate curved staircase. It is now demolished.
Blaquiere was the fifth son of Jean de Blaquiere, a French merchant who had emigrated to England in 1732, and his wife Marie Elizabeth de Varennes. He at first served in the Army, in the 18th Dragoons (later the 17th Dragoons), where he achieved the rank of Lieutenant-Colonel.
In 1771 Blaquiere was appointed Secretary of Legation at the British Embassy in Paris, a post he held until 1772. The latter year Lord Harcourt, HM Ambassador in Paris, was appointed Lord Lieutenant of Ireland, and Blaquiere joined him as Chief Secretary for Ireland.
He became a Privy Counsellor the same year and was appointed a Knight Commander of the Bath two years later.
Blaquiere was to remain Chief Secretary until Harcourt's resignation in January, 1777. He had been elected to the Irish House of Commons for Old Leighlin in 1773, a seat he held until 1783.
After a few months for Enniskillen in 1783, he sat then for Carlingford from 1783-90; for Charleville from 1790-98; and for Newtownards from 1798 till the Act of Union in 1801.
In 1784 Blaquiere was created a baronet, of Ardkill in the County of Londonderry; and in 1800 he was raised to the peerage as 1st Baron de Blaquiere, of Ardkill in the County of Londonderry.
Lord de Blaquiere also sat as MP for Rye from 1801-02 and for Downton from 1802-06.
I HAVE BEEN so far unable to find any record of the de Blaquieres owning a residence in County Londonderry, despite the name Ardkill being in their territorial title.
It is, perhaps, more likely that they simply owned land.
The Ardkill estate, Clondermot, County Londonderry, by marriage: The estate was bought for him by Alexander Tompkins, of Prehen, County Londonderry, father of Maria Tompkins (wife of Robert Dobson), and grandfather of Eleanor Dobson, the 1st Barons' wife.
