OBITUARY. Judge John H. McCunn. John H. McCunn, until recently a Judge in the Superior Court, died suddenly, yesterday morning at his residence, No. 208 West Twenty- first-street. The event, when announced, pro- duced a profound impression in the City, as Mr. McCunn's removal from office had been so re- cent. It appears that he returned home from the State Capital on Wednesday night much fatigued by the heat and his journey, being also exceedingly excited mentally over the action of the Senate in finding him guilty of malconduct and malfeasance in office, and voting for his re- moval from the Bench. He expressed the opinion to his family "that he would not live through the trial he was being subjected to, and thought that he had been cru- elly treated." He walked his room during a great portion of the night, but at last was com- pelled to go to his bed, an attack of pneumonia having completely prostrated him. He talked to his brother-in-law, Dr. Gano, incessantly about his "disgrace," and it was noticed with alarm by his friends that he was rapidly growing worse. He remained in bed all day Thursday and Friday, and in the evening of the latter day becoming very restless. This con- dition continued until about 4 o'clock yester- day morning, when the patient dropped into a gentle slumber. Dr. Gano, who had been in attendance, then left him for half an hour, and on his return found him dead. His wife and family, to whom he was greatly attached, were in great distress at his sudden death, and when the event became known his residence was visited by a large number of his friends and acquaintances. John McCunn was born in Londonderry Coun- ty, Ireland, in 1825, and was in his fifty-seventh year of his age when he died. He was a self- made man, his life being a somewhat remarka- ble one. When a child he conceived a fondness for a sailor's life, and at a very early age shipped on board the ship Ironsides, and landed in New-York in 1841, at the age of sixteen years, without money or friends. He could find nothing to do in this City, so pro- ceeded to Philadelphia, and entered himself as an apprentice to the cabinet-making trade. A few years after he came back to New-York, and worked at the business he had partly learned. It did not suit his restless disposition, and as he aimed at something higher, he determined to be- come a lawyer. He accordingly called upon Mr. Charles O'Conor, at that time a member of the firm of Boardman & Benedict, and stated the object of his visit. Mr. O'Conor, being im- pressed by the young man, gave him a situation as a messenger in his office, and afterward took an interest in his advancement. Having picked up a slight knowledge of law in Mr. O'Conor's office he was admitted to practice at the New-York Bar at the age of twenty-one. When about twenty-three years of age he form- ed a co-partnership with Mr. James Moncrief, which partnership continued for several years to the satisfaction of both parties, the business of the firm being principally confined to matters connected with commercial and real estate transactions. Mr. McCunn about this time became interested in politics, on the Democratic side, with the object of securing the position of Superior Court Judge. The chances of his nomination appearing doubtful, he threw the weight of his influence in favor of his partner, Mr. Moncrief, who received the nom- ination, and was elected. Mr. McCunn then organized a new firm under the title of McCunn, Swartout & Fine, and attached himself to the Tammany Hall party, which subsequently gave him the nomination for City Judge, and he was elected to that office in 1860. He held the position for three years. When the war be- gan he left for Washington with the Sixty-ninth Regiment as a Captain of Engineers. Subsequently he obtained a com- mission as Colonel of the Thirty-seventh Regi- ment New-York Volunteers, which command he recruited himself in this City. He behaved with gallantry at Malvern Hills, and was bre- vetted a Brigadier-General. Having made some disrespectful remarks about his commanding officer, he was ordered to be court-martialed, which he avoided by resigning. Gen. McClellan then issued a general order prohibiting him from ever entering the lines of the army. He was nominated by Tammany Hall in 1863 for Judge of the Superior Court, and was elected, taking his seat Jan. 1, 1864. He was re-elected in 1870, holding the position until the 2d inst., when he was removed. In person Mr. McCunn was agreeable and popular with the rougher classes of society, being always anxious to keep them favorable to him. As a politician, he was mistrusted, even by those with whom he labored.
