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.

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.
