The Rochester Public Library recently added the New Century Atlas of Livingston Co., NY to their collection of digitized books. This 1902 atlas is another one of those that they have been scanning in PDF format. This is another one of those atlases that shows houses with names of owners. It also has schoolhouses, churches and cemeteries. This is the only one I have seen that shows the names of larger farms. This is a large file (38mb) so it may take a little time to view or download.
I was only able to find one relative, George Stockweather, my great granduncle. If you have any family that lived in Livingston County around that time, see if you can find them on this great atlas.
