The first meetings of the Religious Society of Friends were held in the home of William Biles on Biles Island. Falls Monthly Meeting found a site for the first brick meeting house built in Fallsington, about 1690, on 6 acres (0.024 km2) of land that had been donated by Samuel Burgess. Also in 1690, Thomas Janney donated 72 acres (0.29 km2) of land to be used as the Quaker burial grounds for Falls Monthly Meeting.

Fallsington evolved through a succession of periods in American history and architecture. Significant homes in Fallsington range from the late 17th through the Victorian era of the mid-19th century. Fallsington was a center of commerce. In the 1860s a business directory listed blacksmiths, a butcher, carpenters, a carriage builder, a cooper, farmers, an insurance agent, machinists, physicians, a surveyor, and a wheelwright.
The growth of Fallsington continued, with the construction of homes, an inn, public buildings, stores, and small craftsmen's shops. Until the construction of Fairless Hills and Levittown, it was the largest settlement in the Township, and functioned for many years as a commercial center.
- The "falls" of the Delaware River is not a dramatic waterfall but, rather, the rapids that mark the highest navigable point on the river. The names of Fallsington and Falls Township derive from it.
