DENIS CARRIGAN, president of the First National Bank, Custer City, is a native of Canada, born in the city of Montreal, on the 31st of October, 1845. Mr. Carrigan spent his childhood and youth in his native place, receiving a good education in the schools of Montreal, and remaining there until twenty years of age, when he left home to achieve his fortune and carve out his own destiny. In 1866 he went to Omaha, Nebraska, and entered the employ of the Union Pacific Railway Company, remaining with the same until the line was constructed as far west as Sidney, Nebraska, which point was fixed upon as a terminal of a division of the road. Believing that in due time a thrifty town would spring up at this place, and seeing as he thought exceptional opportunities for business advancement, he severed his connection with the company and erected a store building on the present site of Sidney, which aside from the railroad was the first improvement in the town. Buying a stock of general merchandise, he was soon in the enjoyment of a profitable business, which continued to grow in magnitude as the population of the town increased, and in the course of a few years he found himself on the high road to prosperity. In the spring of 1876, when the Black Hills were opened for settlement and Custer City sprang into existence, Mr. Carrigan started a branch store at the latter place, under the management of S. M. Booth, the venture proving remarkably successful. After running the latter store until 1879 he exchanged it for valuable real estate in Custer City, he meanwhile continuing his business at Sidney, which by the time indicated had grown largely in volume and earned him a fortune of no small proportions. In addition to the local trade it supplied various points in the Black Hills with merchandise, thus doing an extensive wholesale as well as a large retail business and proving profitable far beyond the original expectations of the proprietor. In connection with his mercantile interests, Mr. Carrigan also devoted considerable attention to live stock, having come into possession of a fine ranch about thirty-two miles west of Sidney, where he kept large herds of cattle, from the sale of which he realized liberal returns. In the fall of 1880 Mr. Carrigan disposed of his mercantile and real-estate interests in Sidney and the following spring moved to Custer City, where in November of the same year he established a private bank, of which he was sole proprietor and business manager, this being the first financial institution not only in Custer City, but in the southern part of the Black Hills country. Mr. Carrigan managed the institution under the name of the Bank of Custer until 1890, in October of which year it was reorganized as the First National Bank of Custer City, he being elected president, which relation he still sustains. In addition to his position as executive head of the bank, Mr. Carrigan is also the principal stockholder and the institution under his able management has been successful from the beginning, the business at this time being large and far-reaching and second to that of few banks in the state. Mr. Carrigan is a safe and conservative financier, familiar with every branch of the business in which he is engaged, and is well informed upon monetary questions in their relations to the varied interests of the country. In addition to banking he has done considerable in the line of real estate, owning at this time a large amount of city property, besides his ranch, in which he still has valuable live-stock interests. A staunch supporter of the Democratic party and an untiring worker for its success, he has steadily and persistently avoided partisan politics and refused to accept office, although he at one time consented to serve as county commissioner, and also acted for a number of years as school treasurer. Mr. Carrigan is a thirty-second-degree Scottish-rite Mason, also a Knight Templar, and. for a number of years has been a zealous member of this ancient and honorable fraternity. Mr. Carrigan owns a beautiful home in Custer City, the presiding genius therein being a lady of beautiful character and varied culture, to whom he was united in the bonds of holy wedlock on May 24,1871, the ceremony having been solemnized in the city of Cheyenne, Wyoming. Mrs. Carrigan, who before her marriage bore the maiden name of Louisa McWhinnie, is a native of Illinois, but has spent the greater part of her life in the west.
