The Rochester Public Library recently added the Combination Atlas Map of Genesee Co., NY to their collection of digitized books. This atlas originally published by in 1876 by Everts, Ensign & Everts is in PDF format. This was a large atlas approx 27 x 17 inches and makes a large PDF file (80mb) This atlas is one of those that shows property owned and where homes of people are located. Also the maps show schoolhouses, churches and cemeteries.
Within this atlas are some short histories of the Towns in Genesse County. Also there are some illustrations of buildings and larger homes in the County
I found the cemetery were my ancestor, Richard Buell, was buried in 1819 in what is now S. Lyon St. in the City of Batavia. That cemetery was dug up and moved before 1900. I found some of his descendants in the Town of Elba. I also found other distant relations in the Town of Pavilion. See if you can find any of your relatives in this 1876 atlas.
