A one story stone mill was built by Jacob Becker in 1779. The second story was added about 1800 by Benjamin Longnecker; who ran the mill from 1800 until 1808/1810, where upon, Peter Longnecker, Ben's son, got the reins from 1811 to 1815. The mill was sold to Marcus Groff in 1816 and a succession of Groffs, starting with Marcus, then Mark, David 1824, Samuel, and then sold by Daniel in 1862-64. The third story is believed to have been built in c.1855 by either David, Samuel, or Daniel Groff.

The new owners in 1864 were a pair of Christians; Newhauser and Ebersole. In less than a year or two, the mill was aquired by William Ressler. The Ressler era continued with Jacob K. Ressler in 1899. Closer to the modern day, in 1939, W. Franklin Ressler was the owner. It was Ressler's Mascot Mill in 1969. In 1994 it was the Mascot Mill Museum, owned by the Ressler Foundation.

Two turbines were powered from the waters of Mill Creek which was dammed up north of the adjacent Sh 772, funneled under the road via the 300' headrace, and exiting by a 1,300' tailrace back to Mill creek. The 20 barrel/day mill ground flour, grist, corn meal and also powered a saw mill. Today, much corn meal is still ground in the winter for the local Amish farmers. The 1855 brick miller' house is right beside the mill. These and a few other houses and farmsteads made up early day Mascot village.
