A neighboring farmer, Modecai Davis' hiers, aquired the mill and land in 1850. Then in 1877, Allison Alexander did a major remodel, refitting the mill to operate on the then,new and popular roller process; this, in an effort to compete with larger mills in the Midwest and Great Lakes area, where the flour industry had settled.

The Waterloo Mills Historic District, on the National Register of Historic Places, was donated to Brandywine Conservency by Mr. & Mrs. John Haas in February 1998. The 144 acres joined the 53 prior acres already in the Waterloo Mills Nature Preserve in Newton Twp, Delaware Co. and adjoining the Haas donation, to make a total of 167 acres of preserve in the Waterloo Mills Preserve in and along Darby Creek.

Alexander built the small c. 1890 bank barn, which survives-see photo, reconstructed the millpond, starting an ice manufacturing operation. Mill operation continued into the 1900's by Alexander, who sold to the Wilbur Chocolate Co. family in 1909, bringing their holdings at the time to over a hundred acres, including their neighboring "Idlewood Farm". With this purchase, the land ceased to be farmed.

The blacksmith/wheelwright shop across Waterloo Road from the mill on Davis farmland from before 1843. The early blacksmith shop was demolished, presumably when the wheelwright shop was expanded-new blacksmith shop became a part of the expansion by Edward Gallagher sometime between 1891-94. A datestone on the building shows E.D. 1891. Gallagher turned the farm & mill into a large dairy operation in the late 1800's. The blacksmith & wheelwright shops were by Charles Stout in 1850, then by his war vertern son, David B. Stout from 1868-1910.

John Haas' father, Otto Haas, began buying Waterloo Mills parcels iun 1926 and by 1968, pretty much owned the entire hamlet. Haas owner of the Philadelphia chemical conglomerate, Rohm & Haas. The first post office for Easttown Twp. was at Waterloo Mills from 1853-67, inside the mill structure, with tenant miller, William Steel, postmaster.
