Ancestors At Rest has added another Ledger Book online. A Store Ledger from Maine 1922-1927 is freely available as 11 pdf files. The best news is that the first file contains an index of names.
Here's a clip from the C and D indexes. The numbers beside each name refer to the page(s) in the ledger book where the entries for that individual are found.
The next helpful item is that each of the pdf files uses a consistent naming convention - that is with the number of the page in the ledger that is the start of the pdf file. So if we want to find Decker, Chas 6-7 (from the image at the left) we have to look for the pdf file that contains pages 6 and 7.
A quick look shows that the PDF files available for download are: Index, P. 1, P. 23, P. 43, P. 63, P. 85, P. 105, P. 123, P. 215, P. 241, P. 273
So we can see that we want to download the file called P.1. And sure enough as we scroll to pages 6 and 7 we spot the correct name.
It looks like the Decker family needed coffee, raisins, and other assorted household items in 1923. Butter cost the household 30 cents!
Because there is no identifying information in this ledger as to what store it was or the precise location, I searched for several of the individuals found in the index.
Of the 6 people I searched for in the 1920 census on
Ancestry.com, I found 4 of them living in Penobscot Maine.
