Jupiter went on to become a leader in the African American community. In 1787 he delivered a speech to the African Society of New York City entitled “An Address to the Negroes in the State of New York”. In the speech he empathized with their disappointment at not having been emancipated by the new American government, but he cautioned them that it was extremely difficult for the lower classes to earn a living, and they should content themselves with obeying the will of God.
Jupiter Hammon’s death was unrecorded, but historians place it somewhere around 1806. He spent his final years living with John Nelson Lloyd, a great-grandson of Henry. He was buried on Lloyd land, in an unmarked grave.
Lloyd Harbor was a part of Henry’s manor. Fishing and duck hunting in Lloyd Harbor earned fees for Henry. So did hunting on the land, horse grazing, and trapping. The magnificent stands of oaks and chestnuts provided superb masts for the sailing ships of the British navy or colonial trading ships. Henry’s ability to import apple trees enabled him to turn his prolific crops into apple cider and to earn him a considerable sum from his extensive apple cider trading business in the other English colonies and in the Caribbean. The Manor also contained fecund salt and fresh water ponds and enough grazing land to support the large variety of animals needed to supply meat, hides, wool, candles, powder horns, bristles for brushes and plaster, etc., for the Manor and for trade. Together, the natural resources of Lloyd Neck, coupled with the ability to import/export goods, enabled the Manor to flourish under Henry’s guidance.
When Rebecca died, Henry married a widow with children of her own. When Henry died in 1763, he left the Manor to his four surviving sons, Henry II, Joseph, John and James. The sons received unequal portions of the Manor from their father. Henry had paid for James’ medical education in England, and James became the first obstetrician/pediatrician in the colonies. Noting the cost of James’ education, Henry justified his decision regarding the unequal property subdivision. Nathaniel, the son who had pre-deceased Henry, had left only a daughter as a survivor. Since women could not inherit land without it becoming the property of their husbands, Henry left his daughters and granddaughter a sum of money.
