I am interested in finding the sale of property in Ceres in 1819/20 by John or Abram George SIVERLY. Both had property to sell in July 1819 when A. G.'s son, John, stayed there to sell both properties. They moved on to Venango Co., PA. I have searched the records for Allegany Co., NY, but have come up with nothing. Any suggestions will be appreciated. Thanks. Connie Siverly Ferguson
