Wallace family general store account books

 Collection
Identifier: 1004-1
Abstract: The Wallace family general store was a country store established by Robert Wallace (1721-1793) when he purchased land in what is now East Earl Township northeast of the town of Lancaster around 1761. The records of the Blue Ball store are somewhat unusual because they cover a single rural enterprise over a long period that coincides with the change from near-frontier conditions to intensive agricultural development. All of the records are typical storekeeper's account books: day books, ledgers and cash books. There is also an arithmetic copy book, circa 1790, that belonged to Thomas Wallace (1785-1871), the youngest son of Robert Wallace.
