1st Baron Maguire

The Maguires supplied Chiefs or Princes to Fermanagh from about 1264. They were inaugurated at Cornashee, a mound near Lisnaskea. The Maguires possessed all of Fermanagh, hence called "Maguire's Country;"  and maintained their independence as Lords of Fermanagh down to the reign of JAMES I, when their lands were confiscated like other parts of Ulster; but CONNOR ROE MAGUIRE obtained re-grants of 12,000 acres of the forfeited lands of his ancestors. His successors were created BARONS MAGUIRE.

THOMAS MOR MAGUIRE (c1375-1430), Lord or Prince of Fermanagh, chief of the house of MAGUIRE, married Margaret, daughter of Con O'Neill, Prince of Tyrone, and had issue,
Philip, m Deborah Blennerhassett (née Mervyn);
THOMAS, of whom we treat.
The second or, according to some, elder son,

THOMAS OGE MAGUIRE, Prince of Fermanagh, died in 1480.

His lineal descendant, 

SIR BRYAN MAGUIRE (c1589-1633), Knight, was elevated to the peerage by CHARLES II in 1628, in the dignity of BARON MAGUIRE, of Enniskillen, County Fermanagh, with limitation of the dignity to the heirs male of his body lawfully begotten.

He wedded Rose, daughter of Art O'Neill, of Carrickastickan, County Armagh, and sister of Owen Roe O'Neill, and had issue,
CONOR, his heir;
Rory, a colonel in the army.
His lordship was buried in Aghavea, County Fermanagh.

The elder son,

CONOR, 2nd Baron (1616-45), was one of the chief leaders in the rebellion of 1641, and one of its chief victims.

He was tried for high treason in London, 1644, and being found guilty, was hanged at Tyburn.

With him, the title became attainted.

He had espoused Mary, daughter of Thomas Fleming, of Castle Fleming, King's County, and had a son.


ROGER MAGUIRE (c1641-1708), who, but for the attainder of 1641, would have been 5th Baron Maguire, elder son and heir of the Hon Rory (or Roger) Maguire, by his wife Deborah, widow of Sir Leonard Blennerhassett, daughter of Sir Henry Mervyn; succeeded his father in 1648; and had summons to the Irish Parliament which met in Dublin, in 1689, as Baron Maguire, of Enniskillen, and took his seat accordingly.

He was Lord-Lieutenant of County Fermanagh, 1689; and Colonel of an infantry regiment raised by himself, with which he was present at the battle of Aughrim, 12th July, 1691.

Colonel Maguire wedded Mary, daughter of Philip MacHugh O'Reilly, and had issue,
ALEXANDER, his successor;
Bryan Oge;
Rose; Marion; Catherine.
The elder son,

ALEXANDER MAGUIRE, a lieutenant-colonel in Cuconaght Maguire's regiment, retired to France, where he died without an heir after 1719, when the male issue of his father became extinct.

The title, however, continued to be assumed, as under:-

PHILIP MAGUIRE, but for the attainder of 1641, 7th Baron Maguire, uncle and male heir, married Mary, sister of Brigadier-General Gordon O'Neill, and daughter of Sir Phelim O'Neill.

THEOPHILUS or THOMAS MAGUIRE, but for the attainder 8th Baron, son and heir, espoused Margaret, daughter of _________ O'Donnell, of Tyrconnel.

ALEXANDER MAGUIRE (1721-), but for the attainder 9th Baron, entered the French army as Lieutenant Réformé in the Irish infantry regiment of Berwick, 1740; retired on half-pay, 1763; Knight of Saint Louis, 1763.

Several of the Maguire family, many of whom were in foreign service, assumed and were styled Lords Maguire.

Then there was John Rochfort Maguire who was a partner of Cecil Rhodes and a member of King Edward VII's Marlborough House Set. I did a blog item on 2 May three weeks ago under "Gold Fever" about his connections. I wonder where he might fit in?

Previous comment error, I regret, it should be James Rochfort Maguire who was Cecil Rhodes partner and one of King Edward VII Marlborough House Set and not John, apologies.
