“Edmund of Kilnacrott had a son John who had a son Brian, by Mary, daughter of the Baron of Dunsany, who had a famous son Malmore, commonly called Myles the Slasher. This Myles was an able military leader during the civil wars of 1641, and showed prodigies of valor during the years 1641, 1642, and 1643; but, in 1644, being encamped at Granard, in the County of Longford, with Lord Castlehaven, who ordered him to proceed with a chosen detachment of horse to defend the bridge of Finea against the Scots, then bearing down on the main army with a very superior force, Myles was slain at the head of his troops, fighting bravely on the middle of the bridge. Tradition adds, that during this action he encountered the colonel of the Scots in single combat, who laid open his cheek with a blow of his sword; but Myles, whose jaws were stronger than a smith's vice, held fast the Scotchman's sword between his teeth till he cut him down, but the main body of the Scots pressing upon him, he was left dead on the bridge. “This Myles the Slasher was the father of Colonel John O'Reilly, of Ballymacadd, in the County Meath, who was elected Knight of the Shire for the County of Cavan, in the parliament held at Dublin on the 7th of May, 1689. He raised a regiment of dragoons, at his own expense, for the service of James II., and assisted at the siege of Londonderry in 1689. He had two engagements with Colonel Wolsley, the commander of the garrison of Belturbet, whom he signally defeated. He fought at the battles of the Boyne and Aughrim, and was included in the articles of capitulation of Limerick, whereby he preserved his property, and was allowed to carry arms. “Of the eldest son of this Colonel John O'Reilly, who left issue, my friend Myles J. O'Reilly, Esq., is now the senior representative. “From Colonel John O'Reilly's youngest son, Thomas O'Reilly, of Beltrasna, was descended Count Alexander O'Reilly, of Spain, who took Algiers! immortalized by Byron. This Alexander was born near Oldcastle, in the County Meath, in the year 1722. He was Generalissimo of his Catholic Majesty's forces, and Inspector-General of the Infantry, etc., etc. In the year 1786 he employed the Chevalier Thomas O'Gorman to compile for him a history of the House of O'Reilly, for which he paid O'Gorman the sum of £1,137 10.s., the original receipt for which I have in my possession. “Prom this branch of the O'Reilly family was also descended the illustrious Andrew Count O'Reilly, who died at Vienna in 1832, at the age of 92. He was General of Cavalry in the Austrian service. This distinguished man filled in succession all the military grades in the Austrian service, with the exception of that of Field Marshal, and was called by Napoleon '_le respectable General O'Reilly_.'
