JOHN COPCUTT, one of the oldest residents of Yonkers, was born at Oxfordshire, England, in 1805. When twelve years of age his parents removed to New York City, where he was educated in the schools of that place. He followed the vocation of his father, and soon became the largest dealer in and importer of mahogany. He was noted for his extraordinary gift in judging mahogany, and often was laughingly told that "he could see right through a log." In 1824, he made his first visit to this city, accompanied by his father, to make arrangements to have mahogany sawed at the Yonkers mills, coming by sloop from New York. In 1845, Mr. Copcutt purchased a tract of land which included the lower, or first, water power where the Nepperhan River empties into the Hudson, and built upon it a number of mills and stores. In 1854, he made another extensive purchase of woodland and also built his fine stone residence on Nepperhan Avenue. Soon after this he acquired more property and water–power, erecting in the vicinity of his home several substantial factories, besides many small cottages which were rented to the hands employed in the various mills.
