These Hallenbecks lived in the first ward of Albany where he also owned a large tract of land that stretched from the stockade to the Beaverkill and would remain with his heirs for more than a century. He was an Albany mainstay whose city holdings were assessed on a par with the more successful merchants. In 1699, he joined his Albany neighbors in signing a loyalty oath to the king of England. Almost a decade later, his real property still was valued substantially (probably in reference to his extensive lands on the Southside) on the city assessment roll.
Isaac Casperse Hallenbeck filed a will in November 1708. It stated that he was of Albany city and his wife was "of New York City." It named seven living children who would share his property which included an island in the Hudson River above Albany, other land, and personal property. He died in March 1709 and was buried from the Albany Lutheran church. Church records said he was about forty-nine years old!
