Are you tracing the family history of someone who lived in the U.S. during the 20th century? Check out a wonderful free database in the United States called the Social Security Death Index, or the SSDI. Keep reading for 5 FREE online sources for the SSDI,7 tips for searching the SSDI and what you can do with SSDI info.
In 1935 the Social Security Act was signed into law by President Franklin Roosevelt, and consequently more than thirty million Americans were registered by 1937. Today, the Death Master File from the Social Security Administration contains over 89 million records of deaths that have been reported to the Social Security Administration and they are publicly available online.
Most of the information included in the index dates from 1962, although some data is from as early as 1937. This is because the Social Security Administration began to use a computer database for processing requests for benefits in 1962. Many of the earlier records back to 1937 have not been added.
The SSDI does not have a death record for everyone; and occasionally you may find an error here and there if something was reported inaccurately, but overall it’s a terrific resource! It’s especially great for many people who were missed in the 1890 census or whose birth predated vital records registration in their home state. Remember they just needed to live past 1937 and to have worked to have been included. So they could have been born sometime in the later 1800s.
5 FREE Online Sources for the SSDI
Several genealogy websites provide free access to the SSDI, including (click to go right to the SSDI at these sites):
On the Search page, enter your relative’s name and other details you’re asked for. Hopefully you will get back results that includes your relative!
7 Tips for Searching the SSDI
If your relative doesn’t show up in the SSDI, even though you know they worked after 1937 and you know they have passed away, try these search tips:
1. Does the website you are using to search the SSDI have the most current version available? Look in the database description on the site to see how recently it was updated. Try searching at other sites.
2. Make sure that you tried alternate spellings for their name. You never know how it might have been typed into the SSDI database.
3. Many SSDI indexes allow you to use wildcards in your search. So for example you could type in “Pat*” which would pull up any name that has the first three letters as PAT such as Patrick, Patricia, etc.
4. Try using less information in your search. Maybe one of the details you’ve been including is different in the SSDI database. For example it may ask for state and you enter California because that’s where grandpa died, when they were looking for Oklahoma because that’s where he first applied for his social security card. By leaving off the state you’ll get more results. Or leave off the birth year because even though you know it’s correct, it may have been recorded incorrectly in the SSDI and therefore it’s preventing your ancestor from appearing in the search results.
5. Leave out the middle name because middle names are not usually included in the database. However, if you don’t have luck with their given name, try searching the middle name as their given name. In the case of my grandfather his given name was Robert but he went by the initial J.B. But in the SSDI his name is spelled out as JAY BEE!
6. Remember that married women will most likely be listed under their married surname, not their maiden name. But if you strike out with the married name, go ahead and give the maiden a try. She may have applied for her card when single, and never bothered to update the Administration’s records. Or if she was married more than once, check all her married names for the same reason.
7. Don’t include the zip code if there is a search field for it because zip codes did not appear in earlier records.
While most folks will appear in the SSDI, there are those who just won’t. But knowing where information is not located can be as important down the road in your research as knowing where it IS located, so I recommend making a note in your database that you did search the SSDI with no result. This will save you from duplicating the effort down the road because you forgot that you looked there.
What You Can Do with SSDI Information
Now, here comes the most exciting part of the SSDI: what you can do with that information. First, it usually includes a death date (at least the month and year) and sometimes a state and last known residence. Use this information to look for death records, obituaries, cemetery and funeral records. And use that Social Security Number to order a copy of your relative’s application for that number: the SS-5.

How to find 1950 US Census Enumeration District (ED) Maps
The purpose behind them and how to interpret the maps
Ways to use the maps for your genealogy
This is a follow up to episode 51 on The 1950 Census for Genealogy. In that episode I discussed the importance of finding your ancestors’ enumeration district numbers in order to be able to find them when the digitized images are released (before the index is available.) In this episode I will walk you through how to locate the enumeration district (ED) number and then find the actual 1950 US Census ED map. We’ll wrap things up with a quick update on the release of the 1950 US Federal Census.

As I mentioned in Elevenses with Lisa episode 51 The 1950 Census for Genealogy, prior to 1880, U.S. Marshalls were the enumerators for the federal decennial census. Starting with the 1880 census enumerators were hired and they were each assigned an enumeration district, also known as an ED. These districts had to be mapped out so that the enumerators knew the area they were responsible for counting. Therefore, maps are drawn in anticipation of each census being taken, including the 1950 census.

About the 1950 US Census Maps
It’s always important to understand the purpose of a record or source, and the 1950 Enumeration District maps (ED maps) are no exception. Unlike most maps where it’s all about accurately drawing up the current roads and geographical features, census ED maps are drawn up for the purpose of defining boundaries for the purpose of counting people. This means as we look at ED maps we need to keep a few things in mind.
The first thing to understand is that the 1950 ED maps were not necessarily up-to-date with the lay of the land in 1950. Not all streets, parks and features will be included. The reason for this is that the maps themselves were not created for this purpose. Existing maps were used and then enumeration district boundaries were drawn on them.
Maps came from a variety of sources including but not limited to county and City Planning Commissions, 1940 census bureau tract maps, and city engineers. In fact, from a mapping perspective the variety of maps in the collection are fascinating.
Look for the map title, description, legend and census stamps typically found in one of the corners. In this example (see image) from Aurora, Colorado the map used was originally created by the city engineer in 1946 and was revised in 1947.

Following the end of World War II, the United States was growing at a quick pace in 1950. This is particularly true of the newly emerging suburbs. Therefore, if your ancestors built a new home in a new development in 1949, don’t be surprised if you don’t see the street on the 1950 census ED map. However, rest assured that the maps still hold value for your family history as they provide many interesting and unique details about the area surrounding your ancestors’ homes.
Each map was stamped with a small legend where the meaning for each of the colored lines drawn could be indicated. From my random sampling of 1950 census maps across the United States it appears that the coloring coding was consistent as follows:
Red = Township
Green = Corporate Limits/Ward
Orange = Enumeration District
Expect to see errors, inconsistencies and omissions in the maps. The more rural the area the more likely the map was compiled from several sources by the Census Bureau cartographers. This compilation created more opportunity for errors, and often used older maps.

The Meaning of Census Enumeration District Numbers
A census enumeration district number is made up of two numbers separated by a dash. The first number (in this example: 1) represents the county/region. The second number represents the area within the county that could be covered by an individual census enumerator within the amount of time provided for taking the census, about 2-4 weeks. The official start of the 1950 US Federal Census was April 1, 1950.

How to Find 1950 Census Maps
Some 8,000 census maps have been digitized and are available at the National Archives. However, the National Archives website can be challenging to navigate. I recommend using the Unified 1880-1950 Census ED Finder Tool at Steve Morse’s website.
1. Go to https:/stevemorse.org
2. In the menu in the upper left corner hover over US Census and in the secondary menu click Unified 1880-1950 Census ED Finder
3. Select the state from the first drop-down menu.
4. Next select the county.
5. Then select the city.
6. You will then see many enumeration district links listed. In order to find the right one for your ancestor’s home, enter the house number and select the street from the next drop-down menu. Don’t worry about directional parts of the address like west or east unless they are offered in the list of street names.
7. As soon as select the street name, the list of ED numbers should be reduced. In this example we are down to three.
8. To further reduce the possible ED numbers, we can select Cross or back street on same city block. If you’re not sure what the neighboring streets are, click the see Google Map This will plot the address you entered into Google Maps where you can then find the closest cross street, and the next streets over. If the address is not precisely marked on the map, check the address that appears in the Google Maps search box.
In my case, the One-Step tool didn’t allow me to specific W. Arcade, so Google Maps just gave me the general area, and not the address. By adding the W. to the address and pressing enter on my keyboard Google Maps was able to precisely plot the location. Now we can make note of the closest cross street (ex. N. Center), the street north of the address (E. Monterey Ave.) and the street south of the address (W. Noble St.)
9. Head back to the Unified 1880-1950 Census ED Finder page and enter each nearby street (you can enter multiple.) This should reduce the ED numbers one. This is the ED that includes your ancestor’s address.
How to Find 1950 Census Maps
1. Make note of the ED number, and then go back and click the button that says See ED Maps for ____________ County. You could have clicked this button without going through the process of locating the ED number, but the ED number makes it much easier to find your ancestor’s home street on the map. This number will also assist you in being able to find your ancestors in the 1950 census before it is indexed.
2. You will now be on the Viewing 1950 Enumeration District Maps in One Step Re-enter the city from the drop-down menu.
3. Click the Get ED Map Images You will receive two links. The first link is Links to NARA viewer will take you to the page on the National Archives website which includes all of the information about the map and the record hierarchy. Source citation information can be gathered from this page.
5. Click the second link called Direct links to jpegs on NARA server. This will take you to the image by itself as hosted on the National Archives website. I find this the easiest way to save the full resolution image to my computer hard drive. On my PC I right-click on the map and select Save Image As.
This page is also important if you want to use this image in another program such as Google Earth. The URL for this page is the direct URL to the image. Notice that it ends in .jpg. This means that it is the image alone, and this link can be used to create a custom map overlay in Google Earth. You can see an example of a custom map overlay in my video Create a Family History Tour with Google Earth Pro at the 06:13 mark.
