As sole-surviving son, he inherited the Manor of Rensselaerwyck when he was 5 years old; upon his death, in 1769, the Manor was administered by his brother-in-law
Abraham Ten Broeck (who also served as
Mayor of Albany from 1779 to 1783 and, again, from 1796 to 1798) until his son, [Stephen van Rensselaer III], came of age, who served as the tenth Patroon of Rensselaerwyck from 1785 to 1839. At the age of twenty, Stephen II was commissioned a captain in the Albany County Militia. Shortly after his 1764 marriage, he built the new Manor House in 1765, "from where he sought to rehabilitate the manor that had lacked active leadership since the death of his father almost two decades earlier." ==Personal life==
