Isaac Vosburgh was born in July 1720. He was the eldest son of Abraham and Geertie Vandenbergh Vosburgh. He grew up in a large family in the first ward home of a newcomer brickmaker. Before 1740, however, his father relocated the family to the Hoosick Valley. He sometimes was referred to as "Isaac A. Vosburgh."
By 1748, he had married Catharina Van Woert. Four children were christened at the Albany Dutch church before Catharina's death in April or May 1757. In January 1759, church records identified him as a widower when he married Catharina "Taat" (probably Staats) of "East Camp." By 1775, six more children had been christened in Albany where both parents were regular baptism sponsors.
Isaac Vosburgh was paid from the city treasury in July 1768. However, additional references to Isaac Vosburgh for mid-century have been scarce.
In 1766 and 67, the West Manor property of Isaac Vosburgh was accorded modest assessments.
In 1790 the Albany census configured the household of an Isaac Vosburgh in the first ward and that of another same-named individual in Watervliet. The assessment roll for 1799, valued his property in the same Albany location.
