The original mill ca. 1750, grist mill and saw mill, was built by Philipp Jacob Probst and his sons, Michael, Valentine, & Martin on their farmstead at the later townsite of Fetherolffsville on a branch of Maiden Creek-later Ontelautee Creek. They also began to acquire more land south of Shochary Ridge, located to the north of their farmstead. By 1759, the sons were three of the four wealthiest people in Albany Twp. Before, they had to haul their grain to Oley, 20 miles south.

Philipp Jacob was a potter in Oberseebach (now Wissembourg), Alsace, northeastern France, but making pottery was not a practical way to make a living in America, so he became a farmer and miller. Anything they wanted to buy or sell necessitated a trip to Philadelphia, about 80-90 miles distant. Philipp Jacob, born in 1692, was the son of Christophel Probst.

A cabin or perhaps a spring house (although almost to large for a spring house) down by the creek, below the store/residence.

The original Valentine Probst (Brobst) house still stands and is in great condition. A stone inn the foundation has 1737 engraved thereon. The owner and operator of the mill and store in 1862 and 1876 was Nathan Trexler. Nathan Trexler, father of Ms. Jonas Kunkel, was born on Jan. 11, 1818 in Albany Twp., Berks Co. He was a farmer and owned two farms, renting out the larger and conducting the smaller. He also operated a custom mill and a general store. He married Lydia Bauscher and together they raised five children, were German Baptist in religious beliefs. Nathan died in Sept. 1879.

The current walkway to the house is now made up of old millstones. The owners in the 1930' were Ralph & Mabel Lutz, then the Dritski family in the 1950's, and fially Joseph & Barbera Freeman in the late 1990's. The millstones were from Martin & Valentine Bropst's mill/Nathan Trexler mill that used to operate across the raod.

The house remained in Brobst hands until the 1900's, even though Nathan Trexler operated the mill and store from the last half of the 1800's.
