Сьюикли: История, этимология и современность города.

Historian Charles A. Hanna suggested "Sewickley" came from Creek words for "raccoon" (sawi) and "town" (ukli). According to Hanna, the Asswikale branch of the Shawnee probably borrowed their name from the neighboring Sawokli Muscogee before the former's migration from present day South Carolina to Pennsylvania. Contemporary accounts from noted anthropologist Frederick Webb Hodge and the Sewickley Presbyterian Church, as well as the current Sewickley Valley Historical Society concur to varying degrees with Hanna's etymology. Some locals alternatively consider Sewickley to be a Native American word meaning "sweet water."

The valley surrounding the Big Sewickley Creek was surveyed in 1785 and sold to American Revolutionary War veterans. After the Battle of Fallen Timbers in 1794, settlers began to trickle in to the area, with flatboats, keelboats, and steamboats forming an industry along the Ohio River. In 1837, the Edgeworth Female Seminary was moved from Pittsburgh to what was then called Sewickley Bottom.
