With equal land taken from Upper Merion and Lower Merion townships, West Conshohocken became an incorporated borough on October 16, 1874. The 602 acres were called Balligomingo, the Indian name for the area. The land was given to William Penn by the Unami tribe of the Lenni-Lenape nation of Indians in the Treaty of 1683. This change occurred because of the area’s new industrial character as a river town with a large number of mills and other industries dependent upon water for power.
