About 1813, Thomas Lea is credited with naming his mill, and by association the emerging hamlet where it was located, Auburn. That name endured until 1872, when the Wilmington & Western Rail Road Company laid the track that would connect Wilmington to Landenberg. It included a stop at Yorklyn, marked by a Post Office and water tank alongside snuff, paper and woolen mills. What prompted the railroad to choose the name remains a mystery.
By the early 1900s, Yorklyn was a mill town of less than 300 people, most of whom lived in company-owned houses. Residents worked in the local mills, shopped in local family-run stores, supported the Yorklyn School, and cheered local ballplayers as they enjoyed “America’s pastime.” A 1903 brochure promoting a new trolley line through the region predicted growth and prosperityfor Yorklyn: "Possessing, as it does, the foundations of a thriving town, Yorklyn will undoubtedly experience vast changes within the next few years; its pleasing scenery and delightful location being bound to attrackthe house-seeker and the investor."
To this day, Yorklyn remains an "unincorporated community" in Delaware, and residents who desire home postal delivery must adopt a Hockessin address. Therefore, Yorklyn remains a village without official boundaries - but with boundless potential for what the future holds.
This 1881 map of New Castle County, Delaware (based on actual surveys and records) featured “(Auburn)/Yorklyn P.O.,” reflecting the town’s name change and the addition of a U.S. Post Office in 1872. It included the 1869 Yorklyn School, the Garrett Snuff Mill and the original Woolen Mill that would become the Marshall Brothers paper mill in 1890.
