Many thanks to BRANDON BELLINGER for contributing this Ledger Book of Ancestor, John Gratton. Brandon has also sent in the Ledger Book for 1828 which will be completed soon. There are lots of names listed throughout and gives an idea of what business your ancestor may have been in. Here are the ledger entries for 1827 and 1828. I have also attached a glossary (below ledger)to help define some of the words used in the ledger.
