Wiconsico, PA

Wiconisco is a census-designated place in Wiconisco Township, just north of U.S. 209 and the borough of Lykens. The 2010 census counted 921 people. The place's name comes from Wiconisco Creek, and a post office has operated here since 1835. The Census Bureau's 2010 record spells the CDP Wiconsico, while local and historical references use Wiconisco, a small spelling difference that shows up in the county record.

The creek and the post office give this part of Dauphin County a clear local map. Wiconisco sits in the Lykens Valley, close to the road and borough connections that organize the surrounding communities. Its early mail service predates the modern census designation by well over a century, and the creek name preserves the older geography. Wiconisco is a small place whose most useful clues are right in its name, its waterway, and the postal route that has served it since 1835. The spelling difference is small, but it is part of the place's paper trail.
