BY FRANCIS P. BLAIR.

In memoirs of individuals of distinction it is usual to look back to their ancestry. The feeling is universal which prompts us to learn something of even an ordinary acquaintance in whom interest is felt. It will indulge, therefore, only a necessary and proper curiosity to introduce the subject of this notice by a short account of a family whose striking traits survive in him so remarkably. General Butler's grandfather, Thomas Butler, was born 6th April, 1720, in Kilkenny, Ireland. He married there in 1742. Three of his five sons who attained manhood, Richard, William and Thomas, were born abroad. Pierce, the father of General William O. Butler, and Edward, the youngest son, were born in Pennsylvania. It is remarkable that all these men, and all their immediate male descendants, with a single exception, (who was a judge,) were engaged in the military service of this country.

The eldest, Richard, was Lieut. Col. of Morgan's celebrated rifle-regiment, and to him it owed much of the high character that gave it a fame of its own, apart from the other corps of the Revolution. The cool, disciplined valor which gave steady and deadly direction to the rifles of this regiment, was derived principally from this officer, who devoted himself to the drill of his men. He was promoted to the full command of his regiment sometime during the war, (when Morgan's great merit and services had raised him to the rank of general,) and in that capacity had commanded Wayne's left in the attack on Stony Point. About the year 1790, he was appointed major-general. On the 4th of November, 1791, he was killed in St. Clair's bloody battle with the Indians. His combat with the Indians, after he was shot, gave such a peculiar interest to his fate that a representation of himself and the group surrounding him was exhibited throughout the Union in wax figures. Notices of this accomplished soldier will be found in Marshall's Life of Washington, pages 290, 311, 420. In Gen. St. Clair's report, in the American Museum, volume xi. page 44, Appendix.

William Butler, the second son, was an officer throughout the revolutionary war; rose to the rank of colonel, and was in many of the severest battles. He was the favorite of the family, and was boasted of by this race of heroes as the coolest and boldest man in battle they had ever known. When the army was greatly reduced in rank and file, and there were many superfluous officers, they organized themselves into a separate corps, and elected him to the command. General Washington declined receiving this novel corps of commissioned soldiers, but in a proud testimonial did honor to their devoted patriotism.

Of Thomas Butler, the third son, we glean the following facts from the American Biographical Dictionary. In the year 1776, whilst he was a student of law in the office of the eminent Judge Wilson of Philadelphia, he left his pursuit and joined the army as a subaltern. He soon obtained the command of a company, in which he continued to the close of the revolutionary war. He was in almost every action fought in the Middle States during the war. At the battle of Brandywine he received the thanks of Washington on the field of battle, through his aid-de-camp Gen. Hamilton, for his intrepid conduct in rallying a detachment of retreating troops, and giving the enemy a severe fire. At the battle of Monmouth he received the thanks of Gen. Wayne for defending a defile, in the face of a severe fire from the enemy, while Col. Richard Butler's regiment made good its retreat. At the close of the war he retired into private life, as a farmer, and continued in the enjoyment of rural and domestic happiness until the year 1791, when he again took the field to meet the savage foe that menaced our western frontier. He commanded a battalion in the disastrous battle of Nov. 4, 1791, in which his brother fell. Orders were given by Gen. St. Clair to charge with the bayonet, and Major Butler, though his leg had been broken by a ball, yet on horseback, led his battalion to the charge. It was with difficulty his surviving brother, Capt. Edward Butler, removed him from the field. In 1792 he was continued in the establishment as major, and in 1794 he was promoted to the rank of lieutenant-colonel commandant of the 4th sub-legion. He commanded in this year Fort Fayette, at Pittsburg, and prevented the deluded insurgents from taking it, more by his name than by his forces, for he had but few troops. The close of his life was embittered with trouble. In 1803 he was arrested by the commanding general—Wilkinson—at Fort Adams, on the Mississippi, and sent to Maryland, where he was tried by a court-martial, and acquitted of all the charges, save that of wearing his hair. He was then ordered to New Orleans, where he arrived, to take command of the troops, October 20th. He was again arrested next month; but the court did not sit until July of the next year, and their decision is not known. Col. Butler died Sept. 7, 1805. Out of the arrest and persecution of this sturdy veteran, Washington Irving (Knickerbocker) has worked up a fine piece of burlesque, in which Gen. Wilkinson's character is inimitably delineated in that of the vain and pompous Gen. Von Poffenburg.

Percival Butler, the fourth son, father of General Wm. O. Butler, was born at Carlisle, Pennsylvania, in 1760. He entered the army as a lieutenant at the age of eighteen; was with Washington at Valley Forge; was in the battle of Monmouth, and at the taking of Yorktown—being through the whole series of struggles in the Middle States, with the troops under the commander-in-chief, except for a short period when he was attached to a light corps commanded by La Fayette, who presented him a sword. Near the close of the war he went to the South with the Pennsylvania brigade, where peace found him. He emigrated to Kentucky in 1784. He was the last of the old stock left when the war of 1812 commenced. He was made adjutant-general when Kentucky became a State, and in that capacity joined one of the armies sent out by Kentucky during the war.

Edward Butler, the youngest of the five brothers, was too young to enter the army in the first stages of the Revolution, but joined it near the close, and had risen to a captaincy when Gen. St. Clair took the command, and led it to that disastrous defeat in which so many of the best soldiers of the country perished. He there evinced the highest courage and strongest fraternal affection, in carrying his wounded brother out of the massacre, which was continued for miles along the route of the retreating army, and from which so few escaped, even of those who fled unencumbered. He subsequently became adjutant-general in Wayne's army.

Of these five brothers four had sons—all of whom, with one exception, were engaged in the military or naval service of the country during the last war.

1st. General Richard Butler's son, William, died a lieutenant in the navy, early in the last war. His son, Captain James Butler, was at the head of the Pittsburg Blues, which company he commanded in the campaigns of the Northwest, and was particularly distinguished in the battle of Massissinnawa.
