Bronx County, New York was then established in 1914. Prior to its annexation in 1875, the area now known as Bronx County was actually part of Westchester County. It is believed that the county is named for a Swedish sea captain, John (or Jonas) Bronck, who settled in the area in 1639 and established a farm and that many of the wealthy of Manhattan would come to visit their friends who owned the farm, and would simply say that they were going to the Broncks'. The Battle of Pell's Point would be fought on present-day Bronx County. This battle would be a decisive battle, as it allowed Washington's army an opportunity to retreat to White Plains, New York and would save the Revolution. Up until the 1890's, the area known as Bronx County was a rural farming community. In the 1890's, trolley lines fed into the area and life changed.
