Bryan Mulcahy (in-person at EQL): “Sanborn Fire Insurance Maps and Genealogical Research”
The Sanborn Maps were originally created for assessing fire insurance liability in urbanized areas in the United States. The maps include detailed information regarding town and building information in approximately 12,000 U.S. towns and cities from 1867 to 2007. These maps differ in that they do not list the names of property owners, but display buildings by their street addresses. One may find a house on the Sanborn map and discover something about the structure itself, including its relative position to other houses on the same street or block. When combined with a city directory, which usually includes a "reverse" directory, (a list of residences in numerical order based upon street addresses), an interesting diagram of the neighborhood is produced for research. This seminar will provide an overview of the information provided by Sanborn Fire Insurance Maps.
Following Bryan’s presentation and a short break, we will re-group to share our experiences with Sanborn maps and other sites used for maps and any related mapping tools.
