You may not be aware that beginning in the 1700s or even much earlier, books that listed the names, addresses and ethnicity of all of the businesses and people in a town or city was very common. It was natural, when telephones were invented, to add the telephone number of residents. Telephone directories are a fairly new item in comparison. Also, local tax records usually indicate where and when people lived in a particular place. Since determining the exact location of an event in an ancestor's life is often crucial in determining his or her identity, any resource that can give an exact location is invaluable. This class will focus on city directories and parcel maps.
