"The first European settlers to Sellersville came by way of the Minsi Indian Trail about 1730. The trail later became Bethlehem Pike. By 1742 the Weekly Post stage coach line was established, taking riders from Philadelphia to Bethlehem. In 1742 Jan Jensen built his 3 1/2 story house on 102 acres around the Branch Creek. The first tavern license was issued to Louis Weikel in 1753...later, in 1790, Samuel Sellers bought the tavern lot and four acres around the Branch Creek.

Legend has it that in 1777 the Liberty Bell, and the men who carried it, stayed at the Washington House on their way to Bethlehem to escape the British.

Around 1815 the town took the name of Seller's Tavern from its most famous citizen: Samuel Sellers. By then he was both High Sheriff and a member of the Pennsylvania State Legislature. His son Elias was the first postmaster. He operated the postal service right out of the tavern. Travelers riding the Weekly Post stage coach were required to check their gun with the bartender before taking a room at The Washington House. Legend has it that the twenty drawers behind the bar correspond to twenty rooms in the hotel. "
