This is a quote from Mr. Shaner in a book he's been working on about the Schuylkill Canal.
Frick's Locks:
The land contained in Frick's Locks is part of three adjacent tracts of land purchased in 1734 by Swiss immigrant and Anabaptist Johann"hans" Grumbacher, (119 acres), and in 1764 by Peter Grumbacher, son,(69 acres). Each of these three tracts fronted on the Schuylkill River. In April of 1764, Peter bought the 117 acre tract from his mother and siblings, and in September, 1764, he bought the 69 acre tract which bordered the northern edge of the 119 acre tract . In 1770, Peter purchased from his mother the middle 119 acres to put the entir Grumbacher farm in his possession.
