I just found a great old ledger book from a blacksmiths shop in Frederick Ohio. The ledger starts in Jan 1869 and ends in 1879. It has about 4500 names in it, so I think it will be a great data base when I get it online.
The first person listed in the ledger is Eli Sinks. On Jan 11 1869 Eli purchased 3 large bolts for 50 cents.
It will take me some time to get this ledger on line but I will try and do it as fast as possible.
