We have a microfilmed copy of the original Oliver Phelps ledger containing detailed transactions and maps of the Phelps and Gorham Purchase which opened Western New York State to settlement in 1788. 

We are continually updating our indexes, particularly our surname files and newspaper lists of deaths and marriages post -1875.
