Hello List, If you have confidence your ancestors were in a specific location during the time of a census but they do not show up in the online indexes, this method may help you find them. I have used this to find individuals on Ancestry.com. This works if you have an address from a Street Directory or other records for the period. It worked well for me in searching areas such as Philadelphia and New York where the street names have not changed over the years. If the street you are looking for no longer exists on today's maps, you will need to determine the location from old maps or street directories. You will need good map software such as Microsoft Streets and Trips which shows the names of all streets. Step 1 Locate the address on your map software. Look at the surrounding streets which may have been used as ED boundaries. Print a copy of the map. Step 2 Go to the online census or other source which shows the description of the enumeration districts in the County, Township and/or City you are searching. Copy and paste the descriptions in a word document. Use the FIND tool in your word program and enter the name of the street your ancestors were living on and highlight it each time it appears in the ED descriptions with a color. Enter the names of other surrounding streets and use the FIND tool to locate the street each time it appears. I find using a different color for each street makes it easier to quickly scan the finished document in a large city or town. Step 3 Locate the EDs that have the most highlighted street names. These are the EDs you can concentrate on for a page by page search of the census. Outlining these EDs on your printed map may help you see the order in which you want to search these targeted Enumeration Districts. Hope this helps someone. This is an accumulation of some tips I have read in the past. Perhaps one of our readers can suggest a method for doing this on a MAC computer. I am not familiar with the programs available for MAC users. Mary Ann Westfall, (DCGS)
