Christi, Sometimes you can find an old map that is sectioned off by number (I used one like this at the Carnegie Library in Pgh) --- it has been a long time since I used it so this is all a vague memory for me --- that references a list with the same map. Somehow, from the list provided with the map (the map I used was in an old book), I was able to locate the ED. This is the best I can do right now for you but maybe someone on the list would know what type of map it was I used. There was no title that I remember on the book (it might have worn off) but it just seemed to be a book of maps of the city of Pgh --- perhaps you could find one for your areas of interest?? It is a long shot, perhaps, but it sounds like something that would help you. If you have a sub at Ancestry or a trial sub, something else you might try is scanning through the ED descriptions and narrowing your search to those EDs mentioning the name of your street of interest. Something else you might use is Mapquest. I know that Mapquest is current and street names have changed quite a bit but it was helpful to me (though it took some work) when I tried to find my Grandmother in Brooklyn in the 1920 census. Cindy
