Easiest way to find your people is just to rent a roll of 1920 soundex film. Many public libraries that have an interlibrary loan service can order they for you at a nominal fee for postage & handling. BTW, Ohio will not have any soundex help for the 1930 census to be released next month. The areas covered by the E.D. (enumerating districts) number changed from one federal census to the next. Some large research libraries do have a few overlay maps for really big cities. Have used one for Detroit & Cleveland many many years ago. Perhaps they have a new and better system now. There were never any cities that large in this county. Of course you may view them all at the National Archives & and its various branches. The maps are arranged by the state, county,& then locality and are in Record Group 29. I used them in D.C. a few times. They are listed in the CARTOGRAPHIC RECORDS of the BUREAU of the CENSUS. They are usually annotated to show boundries and numbers and span the census years 1860-1940. Really valuable for those states without the help of the soundex/miracode system. -- Nancy M.
