Historic Iron Forge and Settlement 
The forge which stood in a hollow less than two miles north of Downingtown in the early days was built by Sam Hibbert and named for his two daughters, Mary and Ann. Eventually he sold the Mary Ann Forge to an ironmaster by the name of John Dowlin. The forge and neighboring houses evolved in the course of time from Dowlin's Forge to Dowlin.
Note  — Dowlin forge was operated by John Dowlin starting in 1801, then William Dowlin and then Augustus Dowlin until about 1870. Augustus was my great-great grandfather. Sometime this summer we hope that Uwchlan Township will be publishing my great grandmother's diaries for 1864 and 1865. She, Mary Jane Dowlin, was the oldest child of Augustus Dowlin and Sarah Phillips and grew up at the forge.
