How Cementon came to be

From Wikipedia’s history of Cementon.

Cementon was originally known as "Siegfried's Ferry" as it is located directly across the Lehigh River from Siegfried, one of the three villages that would merge to become Northampton in 1902. In 1828, a bridge was built across the river, and the town became known as Siegfried's Bridge. After a large Whitehall Portland Cement Works quarry and mill were established in 1900–01, the town was renamed "Cementon".
