History
Duncanville, later called Widnoon, appears in the 1876 Atlas of Armstrong County, Pennsylvania. Duncanville was named after James Duncan who established a store there in 1854.

The United Brethren and the Presbyterians had organized churches here and houses of worship in 1878 which were no longer in use by 1913.

Widnoon lies on tract No. 314, covered by warrant 2868, called "Elliott Grove," which adjoined the original line between Toby and Red Bank townships on the east. This tract was originally owned by Willink & Co., Wilhelm Willink being one of several Dutch investors in the Holland Land Company.
