John Leonard Hardenbergh, the author of the following Journal, was a native of Rosendale, Ulster County, in the Province of New York, born in the year 1748. He was the son of Leonard and Rachel Hardenbergh, and the youngest of seven children. The family name is one of the oldest in the State, and is prominent both in its colonial and revolutionary annals. As early as 1644, Arnoldus van Hardenbergh a "free merchant" emigrated from Holland to New Amsterdam "with a cargo of wares for sale in the colony." He was soon after selected as one of the original Nine Men of New Netherland, and served in this board from 1647 to 1650.[1] He was followed in, or about, the year 1652, by his brother Johannes van Hardenbergh, also a merchant from Amsterdam, who at this date was purchaser of "a house, lot and garden" on Manhattan Island. (Calendar, Hist. MSS. in office of the Secretary of State, Albany, Part I, vol. iii). The branch of the family that was subsequently settled at Rosendale, is traced to the year 1706, when Johannes Hardenbergh, with six others, obtained from the crown of Great Britain a grant of land which comprised, as computed at the time, 1,500,000 acres, located in Northern Ulster, then including a portion of the present county of Sullivan,--the western boundary extending to, or near the head of, the Delaware river. The terminal syllable of the name, _bergh_, indicates that the earlier ancestors in Holland were from the hills; and it was quite natural that their descendants should have found permanent location in the hilly districts of Shendaken and Shawangunk, stretching westward from the valley of the Hudson; neither is it surprising that they should have loved freedom and have given their best efforts for its establishment in their adopted land. At the outbreak of the Revolution, Col. Johannes Hardenbergh, Jr. was placed at the head of the Committee of Safety for Ulster County--Kingston, its chief town, being at the time the seat of the New York Provincial Congress of which he was also a member. He had ranked as Colonel in the English colonial service, and been active in military affairs as early as 1748, when Sir William Johnson was in command of the New York troops for the defence of the frontier against the French and Indians. He was also given command by the Provincial Congress of one of the earliest regiments raised for the immediate defence of the Hudson above the Highlands, at the opening of the war of Independence, and from his experience and position was enabled to render distinguished service at that critical period. In 1786, three years after the return of peace, he removed from his farm in Rosendale to New Brunswick, N.J., to spend the remnant of his days with his son, Rev. Dr. Jacob R. Hardenbergh, the first President of Rutger's College.
