I love showing people how to use online tools to compare historical maps to modern ones. You can map out your ancestor’s address, check out their neighborhoods “then and now,” map their route to work, see if their old home still exists and more.

Well, the online Smithsonian magazine has created an exciting new interface for six American cities. Now you can compare modern satellite imagery with bird’s-eye views of:

You’ll see great city layouts before the fire that claimed much of old Chicago, the San Francisco earthquake, the Lincoln memorial and more. The historical map of New York City is the oldest, but the other maps capture each city at a critical point in their growth. For each city you can look at a historical map with a “spyglass” mouse-over of a modern satellite image, or vice-versa, as shown in the New York City map on the right. Each map is accompanied by a fantastic Smithsonian article; the historical maps come from the amazing David Rumsey Map Collection.

As many of you know, it’s possible to do something similar (or even better) with Google’s amazing mapping tools. Learn how to do that with these three Genealogy Gems resources:

Love Finding Old Maps Online? Help “Index” Them!

Recently I’ve seen two calls for volunteers to help “georeference” old maps. Basically, you’re tagging the maps in a way similar to tagging photos of people on social media sites. This makes finding old maps online easier and more accurate. It also allows sites to overlay the old and new maps. “Some places have changed significantly or disappeared completely, creating a puzzle that reveals an exciting contrast,” explains the British Library.

These two sites are asking for volunteers:

The British Library Online Gallery. The British Library is asking for volunteers to help georeference 50,000 maps it’s put online. Go right to the site and you’ll see the invitation to help on the home page. You’ll also see that you can click on a tab to search maps that are already georeferenced! The British Library tells its volunteers: “Your name will be credited, and your efforts will significantly improve public access to these collections. Contributors can see the results of their work, as well as the progress of the pilot and other participants, and the top contributor will be publicly announced.”

David Rumsey Historical Maps. This mega-maps site is also looking for volunteers to help add locations to its online map collections. On the home page, click on the left where it says Georeferencer: Help Add Location to Maps.

We blog about maps a lot here at Genealogy Gems. To learn more about using old maps online and for genealogy, go to our home page and search on the Maps category on the lower left side of the page. Additionally, Genealogy Gems Premium members have access to full-length video classes like these:

Canadiana: Canadian Digital Archive and Portal to the Past

CanadianaDo you have Canadian roots? Then Canadiana should be on your list of online resources searched regularly for family history information.

Recently Newswire.ca described Canadiana as “a digital initiative of extraordinary scale,…a joint effort of 25 leading research institutions, libraries and archives working together with the goal of creating Canada’s multi-million page, comprehensive online archive.” Its digital collections chronicle Canada’s past since the 1600s and most of its content is free.

What we especially noticed in a recent peek at this enormous Canadian digital archive:

  • The Héritage Project. This FREE resource “aims to digitize, preserve and make accessible Canada’s archival materials for Canadians and the world. Héritage is also a pathfinder project to determine the best ways to organize and fund ongoing efforts to make all of Canada’s remaining documentary heritage accessible online.” Their large collection of genealogy materials so far includes immigration records, church records, land records, family histories, voters’ lists and more. Military history, government documents and aboriginal records are also well-represented. Tip: check back often! More is coming, like local and regional newspaper digitization and records of the Canadian Expeditionary Forces.
  • The Canadiana Discovery Portal. This gateway to digital collections from 40 repositories points to 65 million pages! Sample subjects include  Ontario genealogy and War of 1812 campaigns. This portal is also free to use.
  • Early Canadiana Online, with 5 million images already and expected to grow to 16 million. This part of the website requires a subscription ($10/month or a year for $100) This is “a full-text collection of published documentary material, including monographs, government documents, and specialized or mass-market periodicals from the 16th to 20th centuries. Law, literature, religion, education, women’s history and aboriginal history are particular areas of strength.” The site describes itself as “the most complete set of full-text historical content about Canada, including books, magazines and government documents.” Tip: scroll down on the home page to click the Genealogy and Local History portal, but don’t ignore the rest of the site!

How to Find Enumeration District Maps

Looking for enumeration district maps for the U.S. Federal Census? You’re not alone!

1940 Census Enumeration District Map, Oklahoma, Wagoner County, http://research.archives.gov/description/5836456

Recently Genealogy Gems podcast listener Michelle in Denver, Colorado, wrote in with this question:

“Where can I find individual enumeration district maps? I don’t need a state-wide map showing the divisions between enumeration districts, but a map showing the numbered households within a single enumeration district.”

My answer: How to find Enumeration District Maps

First, here’s a little back story from the National Archives (U.S.) website:

“An enumeration district, as used by the Bureau of the Census, was an area that could be covered by a single enumerator (census taker) in one census period. Enumeration districts varied in size from several city blocks in densely populated urban areas to an entire county in sparsely populated rural areas.

Enumeration district maps show the boundaries and the numbers of the census enumeration districts, which were established to help administer and control data collection. Wards, precincts, incorporated areas, urban unincorporated areas, townships, census supervisors` districts, and congressional districts may also appear on some maps. The content of enumeration district maps vary greatly.

The base maps were obtained locally and include postal route maps, General Land Office maps, soil survey maps, and maps produced by city, county, and state government offices as well as commercial printers. Census officials then drew the enumeration district boundaries and numbers on these base maps.” (Check out the full article here.)

Enumeration district maps are not available in all years and all locations. 1940 ED maps are available on the National Archives (U.S.) website. (Scroll down to item 3 for instructions on getting to these through the Online Public Access search.) You’ll see that only the enumeration district numbers and street names are marked on the maps. Individual homes are not.

You might be wondering, are there enumeration district maps before 1940? They are limited but the answer is yes. Enumeration District maps are also available for the 1900 through 1930 censuses. You can browse and download the maps for free at FamilySearch. Search for title The United States enumeration district maps for the twelfth through the sixteenth US censuses, 1900-1940.

For censuses before 1900, the government used voting districts as enumeration districts. Find voting district maps in the Library of Congress book, Ward Maps of the United States : A Selective Checklist of Pre-1900 Maps in the Library of Congress.  (The links here lead to WorldCat search results for these titles. WorldCat will tell you about libraries that have these books.) 

Next, turn to the book Cartographic Records of the Census Bureau for a listing of maps available back into the 19th century at the National Archives. It’s available as an ebook which you can read online or download for free from Google Books. This book is an invaluable resource for finding much early maps at available at the National Archives on microfilm. 

 

Enumeration District (ED) Map Finder

If you just want to find the enumeration district number of an address you already know, go to the Unified Census ED Finder at Steve Morse’s One-Step genealogy website.

At the top of the Unified Census ED Finder page start by selecting the census year (currently 1870 through 1950.) Next, enter as much information as you know about the location such as the county. Select the city from the list of cities displayed. You will then be able to enter street-level information. If you select “other” from the city list, you can then type in the city or town name. Continue to follow the prompts and instructions. 

Here are a few more things to keep in mind as you find and use ED maps:

In cities,  there are often two columns of numbers in the census population enumeration (typically on the far left of the page). There’s house number and the number representing the order in which the enumerator visited the house (which has nothing to do with the house number). If you can’t find a relative in once census, pull the address from one census and use it in the Steve Morse database above to pull up the enumeration district for your missing decade.

Sanborn Fire Insurance Map for Genealogy

Sanborn Fire Insurance Maps can be helpful when searching for old Enumeration District Maps.

Depending on the year you are researching, try to locate a Sanborn fire insurance map for the area.  Sanborn maps do include drawings of individual homes and include their house number. Genealogy Gems Premium Podcast Episode 47 is all about Sanborn fire maps. On the show notes page I even include a list of links to many Sanborn map collections, organized by state.

Final Thoughts: The Newest ED Maps Available Online
