From: The History and Antiquities of the Name and Family of Kilbourn, by Payne K. Kilbourne, 1856.  Pgs. 297-302. Aaron  Kilborn is my 3rd great-grandfather and he was married to Almira Richardson, my brick-wall ancestor. (Article is longer, but I condensed it.)
"AARON KILBOURN, born in Killingworth, Sept. 3, 1798; m. Almira Richardson, of Orange, Conn., April 9, 1820, and has had seven children, viz., Aaron Richardson, Mehitable Elizabeth, Almira Phinetta, Esther Farnham, Mary Louisa, George Franklin and Benjamin Hart. 
His natural propensity for the mechanic arts manifested itself at a very early age, in an almost uncontrollable desire to frequent the blacksmith's shops and mills in the vicinity of his home. At the age of eight years, he began to make water-wheels and play with them in the brook; and while yet in his childhood, he built a small saw-mill with which he used to saw boards in imitation of the larger ones that he had seen. The annual visits of the tailor and shoemaker at his father's house, for the purpose of working up the year's supply of clothes and shoes, were hailed by him with delight, as it gave him an opportunity to indulge his taste and ingenuity in those branches of useful industry. All the tools about his father's house, (which were kept for repairing the implements of the farm,) were also early brought into requisition by the young mechanic, in the manufacture of a variety of indescribable articles. These trifling circumstances are mentioned here, simply as indicative of the early development of the "ruling passion" of our kinsman in a department of business in which he has since become so eminent. 
Having prosecuted the usual studies pursued at the district school by lads of his age, when thirteen years old he was apprenticed to a silversmith in East Haddam . He soon found his employment too trifling and monotonous to be pleasant, and felt greatly relieved when set to manufacturing brass clocks. At length his employer took him to Glastenbury to assist in making and putting in operation a set of cotton machinery, on Roaring Brook, under the superintendence of Amos Dean. Here his mind had full scope, and he often felt and said he had never before been so delightfully employed. Soon after completing this contract, his master was engaged to make the machinery for a woollen factory and clothier's works on the site of "Kilborn's Mills," on Salmon River, in the town of East Haddam New Haven New Haven , he was employed by Prof. Silliman, to make and keep in repair the scientific apparatus connected with the laboratory of Yale  College 
In 1840, Mr. Kilborn contracted to make a lot of machinery for the Penitentiary of Georgia, which resulted in his going to Milledgeville in that State, to put it in operation. It consisted of a steam-engine of ten horsepower, with lathes, saws, tenon-machine, mortising-machine and iron-foundry. When he had completed this contract, and was about starting for the north, he was engaged to superintend the labor of the prisoners for a term of years. Accordingly, in the autumn of 1841, he made his second trip to Georgia 
On the night after the inauguration of Gov. Crawford, (Nov. 7, 1842,) while Mr. Kilborn was in New Haven 
While at the south, he was also engaged in finishing the Insane Hospital and in repairing or re-modeling the State House, the Arsenal, several churches, hotels and private houses; and finally erected and put in operation a Cotton Factory — when, his health failing, he returned to his home. During this period, he had also contracted for and sent on to the south more than $50,000 worth of machinery, castings, &c., a large portion of which was the product of Connecticut industry and much of which was from his own works in New Haven. 
About this time the first thousand of Colt's Pistols were ordered by our Government for the war with Mexico Hartford
