Lewis Stuyvesant Chanler

Lewis Stuyvesant Chanler (September 24, 1869 in Newport, Rhode Island – February 28, 1942) was a New York lawyer and politician.

He was the fifth son of John Winthrop Chanler (1826–1877) of the Dudley–Winthrop family and Margaret Astor Ward (1838–1875) of the Astor family. Through his father, he was a great-great-grandson of Peter Stuyvesant and a great-great-great-great-grandson of Wait Winthrop and Joseph Dudley. Through his mother, he was a grandnephew of Julia Ward (1819–1910), John Jacob Astor III (1822–1890), and William Backhouse Astor, Jr. (1829–1892).

Lewis had nine brothers and sisters, including the artist Robert Winthrop Chanler and the soldier and explorer William Astor Chanler. His sister Margaret Livingston Chanler served as a nurse with the American Red Cross during the Spanish–American War. Margaret Chanler was later married to Richard Aldrich (music critic) and lived at Rokeby. Chanler's eldest brother John Armstrong Chaloner married novelist Amélie Rives Troubetzkoy. Chanler and his siblings became orphans after the death of their mother in 1875 and their father in 1877, both to pneumonia. The children were raised at their parents' estate in Rokeby (Barrytown, New York).
