Young Corcoran, then twenty-five years of age, devoted himself to caring for the property of his father, who was growing old. The father died Jan. 27, 1830. Five years later, in 1835, Mr. Corcoran married Louise A. Morris, who lived but five years after their marriage, dying Nov. 21, 1840, leaving a son and daughter. The son died soon after the death of his mother; the daughter grew to womanhood, and became a great joy to her father. She married the Hon. George Eustis, a member of Congress from Louisiana, and died in early life at Cannes, France, 1867, leaving three small children. Mr. Corcoran long before this had become a very successful banker. Two years after his marriage, in 1837, he moved his family to Washington, and began the brokerage business in a small store, ten by sixteen feet, on Pennsylvania Avenue near Fifteenth Street. After three years he took into partnership Mr. George W. Riggs, the son of a wealthy man from Maryland, under the firm name of Corcoran & Riggs. In 1845 they purchased the old United States Bank building, corner of Fifteenth Street and New York Avenue; and two years later Mr. Corcoran settled with his creditors of 1823, paying principal and interest, about $46,000. During the Mexican war the firm made extensive loans to the government, which conservative bankers regarded as a hazardous investment. Mr. Riggs retired from the firm July 1, 1848; and his younger brother, Elisha, was made a junior partner. "In August, 1848, having about twelve millions of the six-per-cent loan of 1848 on hand, and the demand for it falling off in this country, and the stock being one per cent below the price at which Corcoran & Riggs took it, Mr. Corcoran determined to try the European markets; and, after one day's reflection, embarked for London, where, on arrival, he was told by Mr. Bates, of the house of Baring Bros. & Co., and Mr. George Peabody, that no sale could be made of the stock, and no money could be raised by hypothecation thereof, and they regretted that he had not written to them to inquire before coming over. He replied that he was perfectly satisfied that such would be their views, and therefore came, confident that he could convince them of the expediency of taking an interest in the securities; and that the very fact that London bankers had taken them would make it successful. "Ten days after his first interview with them, Mr. Thomas Baring returned from the Continent, and with him he was more successful. A sale of five millions at about cost (one hundred and one here) was made to six of the most eminent and wealthy houses in London, viz., Baring Bros. & Co., George Peabody, Overend, Gurney & Co., Dennison & Co., Samuel Jones Lloyd, and James Morrison.
