I have said that in 1832 there were three counting houses on Water street, meaning such as were engaged in the business of foreign navigation. These were D. & A. Jackson, Nelson & Harlow, and Nathaniel Carver. The oldest and most important was that of D. & A. Jackson, which derived both its business and character from the old firm of Daniel and Charles Jackson, father and uncle of the members of the house. It did not immediately follow in chronological order the old house of Daniel and Charles Jackson, as for a time after the death of Charles Jackson in 1818 Daniel, the surviving partner, formed a partnership with his son Jacob, under the firm name of Daniel Jackson and son, which was dissolved in 1828. In this last year the firm of D. & A. Jackson had its origin. Though as far as the public knew only Daniel and Abraham were members of the firm, that at a later date their younger brother, Isaac Carver Jackson, became associated with them, there can be no doubt. It is within my recollection that the ship Iconium, the last ship built by the firm, was built in 1848 or thereabouts on the Sheepscott river, under Mr. Isaac C. Jackson’s exclusive supervision. The Jackson brothers were a remarkable set of men, six in number, all about six feet in height, gentlemen in bearing and dress, and with their blue coats and brass buttons, and in summer, white beaver hats, white trousers, low shoes and white stockings, their appearance in our streets gave character and expression to the town. They were all confident, self-centered men, who knew what they wanted and how to accomplish it, meddling in no man’s business and permitting no man to meddle in theirs; neither asking for nor offering advice. They had means sufficient to carry out their enterprises and never sought outside of their family and their commanders, the contribution of a timber head to their ships.
