Yonkers (US /?j???k?rz/) is the fourth most populous city in the U.S. state of New York (behind New York City,Buffalo, and Rochester), and the most populous city in Westchester County, with a population of 195,976 (according to the 2010 Census). An inner suburb of New York City, Yonkers directly borders the Bronx and is located two miles (3 km) north of Manhattan at the municipalities' closest points.
The land on which the city is built was once part of a 24,000-acre (97-square-kilometer) land grant called Colen Donck that ran from the current Manhattan-Bronx border at Marble Hill northwards for 12 miles (19 km), and from the Hudson River eastwards to the Bronx River. This grant was purchased in July 1645 by Adriaen van der Donck, the first lawyer in New York City. Van der Donck was known locally as the Jonkheer or Jonker (etymologically, "young gentleman," derivation of old Dutch jong (young) and heer ("lord"); in effect, "Esquire"), a word from which the name "Yonkers" is directly derived. Van der Donck built a saw mill near where the Nepperhan Creek met the Hudson; the Nepperhan is now also known as the Saw Mill River. Van der Donck was killed in the Peach War. His wife, Mary Doughty, was taken captive and ransomed later.
