The Newlin Miller's House was built by William Newlin in the early nineteenth century in West Whiteland Township, Chester County, Pennsylvania, in the narrow valley of Little Broad Run, a tributary of the East Branch of Brandywine Creek. William inherited the land from his father, John Newlin, who bought the land in 1788. He constructed the house and a sawmill which was described in 1858 as a "frame sawmill with stone foundations driven by an 18 foot overshoot wheel with a 5 foot face." The house has 2 stories and is banked into a hill. It is built of "trash stone" and has a frame addition and porch. The saw mill was owned by William Speakman, a local carpenter, from 1876-1895. The mill has since been destroyed.
