Have adresses changed or been renumbered? While trying to map adresses from the 1920s and 1930s on current maps I have trouble. For example, is an East 4th Street address from 1925 the same location today? When did the NE and SW street names appear? Where can I find this kind of information? Thanks for the help... K
