Abraham Ten Broeck was the son of Dirck Ten Broeck (1686–1751) and Margarita (née Cuyler) (1682–1783). He was the brother of Catharine Ten Broeck Livingston, who was married to John Livingston (a son of Robert Livingston the Younger), Anna Ten Broeck, and Christina Ten Broeck, who was married to Philip Livingston, and New York State Senator Dirck W. Ten Broeck, who married Anna Douw (a daughter of Mayor Volkert P. Douw).[3]
His father was a prominent merchant and politician who served as Albany's mayor beginning in 1746. His paternal grandfather Wessel Ten Broeck, was the son of former Albany mayor Dirck Wesselse Ten Broeck. His maternal grandparents were Abraham Cuyler, the brother of former Albany mayor Cornelis Cuyler, and Caatje (née Bleecker) Cuyler, a daughter of former Albany mayor Jan Jansen Bleecker.[4]
Career
Abraham was sent to New York City to learn business with his sister Christina's husband, Philip Livingston. In 1751, at seventeen years old,[4] he was sent to Europe to learn international business after his father's death, returning to Albany in 1752.[2]
Ten Broeck increased his wealth via trade while in Albany. During the 1750s, he was involved in the provincial militia. In 1759, he was elected to the Albany City Council and in 1760, he was elected to the Province of New York Assembly while continuing to serve Albany.[4]
In 1769, his brother-in-law died at age 27 and Ten Broeck was named co-administrator of the Manor of Rensselaerswyck,[4] a position he held until 1784 when his nephew, Stephen Van Rensselaer III, came of age.[2]
After the death of Mayor John Barclay, Ten Broeck was appointed Mayor of Albany in 1779, remaining in office until 1783. In March 1789, he ran for Congress but was defeated by Jeremiah Van Rensselaer. In 1796, Mayor Abraham Yates Jr. died and Ten Broeck was again appointed Mayor of Albany, remaining in office until 1798 when he was succeeded by another nephew, Philip Schuyler Van Rensselaer (1767–1824).
Margarita ten Broeck (1776–1812), who died unmarried.[10]
By the mid-1760s, Ten Broeck was one of Albany's wealthiest men. The Ten Broecks lived in a house that was assessed equally with the Schuyler Mansion and Yates Mansion in 1788. In 1797, it was burned in a fire that destroyed several city blocks.[11] Construction was started on the new home soon after, and the family resided there beginning in 1798 calling the place "Prospect". The historic mansion still stands in Arbor Hill more than 200 years later.[12]
