History
Before the arrival of European settlers, the Lenape people were already in the Delaware Valley. After William Penn's signing of the Treaty of Shackamaxon, Samuel Sellers, the pioneering settler of the Sellers family, came from Derbyshire, England in 1682, with his brother George Sellers. Both brothers purchased two tracts of land totaling and from William Penn. The official survey for the land was not completed until 1690. Over time, Samuel, his sons, and grandsons expanded their land holdings through additional purchases in the surrounding area. George Sellers later died due to an unexplained death involving a tomahawk. Samuel Sellers, the original settler, was a skilled weaver who played a pivotal role in the early industrial development of the region. He is credited with establishing the first twisting-mill in America. Building upon his father's legacy, Samuel's son, also named Samuel, and his grandson, John, continued the family tradition of weaving. The presence of a dam in Millbourne was first documented in an important deed issued by John Sellers on August 27, 1752. John Sellers recognized the potential of harnessing the waterpower of Cobbs Creek, leading to the development of six sites along the waterway. These sites became essential for subsequent generations and contributed to the growth of Millbourne Mills, first called Sellers Mills. During this time, Millbourne was part of Darby Township. But in 1786, Millbourne was separated with other municipalities to form Upper Darby Township. Following John Sellers' passing in 1804, his estate was inherited by his sons, with George receiving the majority of Millbourne. John Sellers II inherited the grist and sawmills, which were already established before 1749. Millbourne Mills were initially operated by James…
