Chancellor John Lansing married Cornelia Ray 8 Apr 1781. Cornelia died in Albany Jan 1834.
At an early period of his life, he entered the office of Robert Yates,
afterwards Chief Justice, as a clerk in the study of the law. He became a member of the military family of General
Philip Schuyler, and during the Revolutionary war was a distinguished member of the State Convention that conducted the
civil and military operations of the State.
Soon after he was appointed Mayor of the City and in 1787 was, with Chief Justice Yates and General Hamilton,
delegated by the State as members of the Convention which formed the Constitution of the United States. The latter two
withdrew from the Convention and were known as anti-federalists. They opposed the adoption of the Constitution principally
because it did not more effectually secu7re the rights of individual States, and to those men and their co-patriots we are indebted
for the ten amended articles which were subsequently made a part of the Constitution.
On his return he was made a Judge of the Supreme Court, and finally Chencellor of the State.
Lansing Manor was built by Chancellor Lansing for his daughter, Frances.
On the 12th of December 1829, Chancellor Lansing left his hotel in NYC to go down to the dock to post
a letter on the steamboat to his family in Albany. He was never seen again. No event had caused a
deeper sensation in the city since the death of De Witt Clinton.1
