The Best Way to Find Free Old Maps at DavidRumsey.com

by Lisa Cooke | Dec 8, 2020 | 01 What's New, Elevenses with Lisa, Maps | 3 comments

Our ability to find our ancestors is rooted in two important pieces of information: the locations where they lived and the time frames in which they lived there. This means that old maps are essential to our genealogy research.

The good news is that there is an abundance of free digitized old maps available online. One of the best resources is the David Rumsey Map Collection website. There you will find over 100,000 free digitized historic maps. These maps span the globe and centuries. They are perfect for bringing geographic perspective to your family tree.

Elevenses with Lisa Show Notes

In this episode 36 of my free webinar video series Elevenses with Lisa I’ll show you how to navigate this ever-expanding free website. Watch the video and then follow along with the show notes in this article. Here you’ll find answers to questions such as:

What’s the best way to find maps at David Rumsey’s map website?
What is the difference between the search tools (Luna Viewer and MapRank Search)?
What are the advanced search techniques for finding the old maps?
How can I download maps at DavidRumsey.com?
Is it OK to use the maps from DavidRumsey.com in my family history projects?

Rumsey Historical Maps in Google Earth

As we discussed in Ways to Use Google Earth for Genealogy (Elevenses with Lisa episode 12) there are approximately 120 Rumsey old maps available for free in Google Earth. You can find them in the Layers Panel under Gallery. Each map is already georeferenced as an overlay for you.

You can also create your own overlays in Google Earth using Rumsey Maps or digitized maps from other sources. I cover this step-by-step in chapter 16 of my book The Genealogist’s Google Toolbox.

Best Strategies for Finding Free Old Maps

Once you’ve exhausted the few hundred old maps in Google Earth, head to the David Rumsey Map Collection website. Rumsey’s collection includes over 150,000 map, over 100,000 of which have been digitized and are available for free on his website.

Copyright and Use Permission

You will probably be anxious to use these wonderful old maps in a variety of ways. The Rumsey website provides clear direction on copyright and use permission. Go to: DavidRumsey.com > Home Page > About > Copyright and Permissions.

The good news is that generally speaking, you are free to download and use the digitized maps for your own personal use.

The Best Way to View the Maps

There are several ways to view maps:

The Luna Viewer: Browse and search 100,000+ maps
The GeoReferencer: Help georeferenced maps, compare maps overlays
MapRank Search: Browse & search 6000 maps by time & place
Google Earth: 120 maps in the Layers panel, 140 can be added
Google Maps: 120 maps included
Second Life: View some in 3 dimensions and at a huge scale. Location: Rumsey Map Islands. Includes a welcome center with hundreds of maps, and a 600 meter tall map cylinder showing hundreds of maps.
The Collections Ticker: Pop-out distraction!
Insight Java Client: Downloadable workspace

Of this list, the best two tools to user are:

The Luna Viewer: Browse and search 100,000+ maps
MapRank Search: Browse & search 6000 maps by time & place

I will show you how to use each. Note that in these examples we will be using a computer to search the site rather than a mobile device or tablet.

The Luna Viewer: How to browse & search the maps

In the main menu under View Collection select the Luna Viewer. Under Luna Viewer click the Launch Luna Viewer button.

The Luna Viewer at David Rumsey Map Collection

Tips for keyword searching:

In most cases it helps to start with a fairly broad search to see the full range of available maps
Be cautious with abbreviations. “MN” does not return “Minn” or “Minnestota”.
Advance search provides you with the use of full Boolean operators like “and,” “or,” “greater than,” “contains,” and others.
After a search, to return to the full collection, click on “show all” under the search button.

Let’s look at an example of using the keyword search in tandem with the Refine column. If you search for New York City, you will be searching all of the data associated with the maps. Since many maps may have been published in New York City, you will likely see many maps for other areas. You can improve this search by going to the Refine column and under Where clicking on New York City.

The Refine column will show you the first five options in each category (What, Where, Who, When). Click More to reveal all of the additional refining options in that category.

Click More to see all refining options in the Luna Viewer

From the returned results, click a map to view it.

You can select multiple items in the Refine column to filter more narrowly. Remove a filter by clicking it under Remove at the top of the Refine column.

Like genealogical records, old maps may include several pages. Look above the blue BUY PRINT button to see the number of Related maps. In my example of a map of the 1939 World’s Fair in New York City, there were two map pages available. Click Related to display all of the available pages.

Click the Related link to view all related map pages.

DavidRumsey.com Advanced Search

The Advanced Search feature can be found in two locations:

Inside the search box – click your mouse in the box and select Advanced Search from the drop-down list
At the bottom of the Refine column on the left side of the screen.

Advanced Search gives you more control over how you search. Let’s look at an example by searching for Sanborn fire insurance maps.

Searching for Sanborn Fire Insurance Maps

The David Rumsey Map Collection website includes many Sanborn Fire Insurance maps. These maps were created for insurance purposes and provide an incredible amount of detail about individual buildings and dwellings in a given neighborhood.

I recommend using the Advanced Search feature to search for these maps. This is because over the years the name of the company as publisher changed.

How to Find Sanborn Maps:

Click on Advanced Search at the bottom of the Refine column
In the “find all of these words” section, click Fields and select Publisher
Type in Sanborn
On the results page, go to the Refine column and Who click More
There are at least six variations of the Sanborn publishing name.

Old Map books and atlases often include valuable historical text often called historical sketches. You can find these using the Advanced search. Search for the exact phrase Historical Sketch. Run this search and then in the Refine column under Where select an area of interest.

How to Download Maps from DavidRumsey.com

Click the map from the results list
On the map’s dedicated page click the EXPORT button at the top of the page.
Select the appropriate size from the drop-down list. (Larger maps may take a few moments to download)
Typically the maps will download to the Downloads folder on your computer

Tips for Selecting Download (Export) Map Size:
Save space on your computer and future headaches by selecting the correct size map for your use. If you plan on using the map to create an overlay or create a nice large print, select the largest size possible ( I recommend at least Extra Large for creating map overlays in the Google Earth.) This will ensure that the map doesn’t appear fuzzy when you Zoom in. High-resolution is also recommended when printing. For example, if you plan on including the map in a book about your family’s history (for personal use, not for resale) a high-resolution map will print crisp and clear. Maps for use on the web or something like a PowerPoint presentation would be fine at lower resolutions.

MapRank Search at DavidRumsey.com

The MapRank Search “app” at the David Rumsey Map Collection website allows you to browse & search 6000 maps by two important criteria: Time & Place.

There are two ways to find the MapRank Search:

In the main menu under View Collection click MapRank Search. Scroll to the bottom of the page and click the Launch MapRank Search
Scroll to the bottom of the home page until you see Featured App – MapRank Search, and click the Launch MapRank Search

How to Find Maps Using MapRank Search:

Start with entering the location name in the search box (in the upper right corner) and click the Find a Place
The location will appear on the modern-day map. The old maps that match the location will appear in the column on the right, prioritized starting with the map that most closely matches what you searched.
Below the modern-day map, move the time slider levers to narrow in on the desired time frame.
Note that the old maps in the results column will change based on the specified time frame.
Broaden the location if desired by zooming out a bit on the modern-day map. Note that the results list will change as you zoom.
Hover your mouse over a map in the results list and notice that a reddish-brown box will appear the selected map and will also appear on the modern-day map. This indicates the area of the map that the old map covers. This will aid you in selecting the map that will suit your needs.
Click a map from the results list and it will open in a new browser tab, although some maps will appear as an overlay on the modern-day map. In that case, click the Luna Viewer button to go to the page where the map can be downloaded.

How to Compare Modern-day Maps with Old Maps

Whether you have found the map by searching with the Luna Viewer or the MapRank Search you will eventually find yourself on the page where the single map is displayed. On the left is the source information.

In the upper right corner of the screen click the View in GeoReferencer button. You will be taken to a page where you can view the old map overlayed on the modern-day map. In the upper right corner move the slider to make the old map transparent so that you can compare between the two maps.

Recap: Comparing the Two Best Search Tools at DavidRumsey.com

Luna Viewer:
– 100,000 maps
– Search, then refine
– Sometimes glitchy interface

MapRank Search:
– 6000+ maps
– More control with time slider & map
– Map results list ranked by closest coverage

Live Chat Q&A: Answers to Your Questions About David Rumsey Maps

One of the advantages of tuning into the live broadcast of each Elevenses with Lisa show is participating in the Live Chat and asking your questions.

From Megan: What is the difference between Google Earth and My Maps?
From Lisa: Google Earth is a free software download. This is where I create what I call family history tours. They are a collection of data points and media that come together as a research tool and storytelling tool. My Maps are created in Google Maps. I prefer creating in Google Earth because it offers more tools and options, and it’s where I keep all my mapping work.

From Gwynn: Heard in the past Java Client might have security holes has this been fixed?
From Lisa: Read more about the latest on Java Client at the website’s FAQ page.

From GeneBuds: Must set up account to use Luna Viewer?
From Lisa: No, you don’t have to have an account to use the Luna Viewer. “Registering for an account allows you to save your work and preferences, search external media, create Media Groups and Presentations, customize your settings, create annotations, and upload your own content.” As I mentioned in the video, I prefer to do all my work in Google Earth.

From Gwynn: Sanborn Fire Maps: Where do I find the Key to the symbols? Are they the same from year to year or do they change?
From Lisa: Here’s the main resource page for Sanborn maps at the Library of Congress. You will find specific information about interpreting the maps including Keys and Colors here.

From Karen: If you are specifically looking for plat maps for our US farmers would you put the word plat in the search field?
From Lisa: I would use the Advanced Search and enter the word plat in the “Find all these words” box. Click the plus sign to add an additional “Find all these words” field and type in the name of the location. If that doesn’t deliver the desired result, omit the location and just search on the word plant. Then, on the results page, go to the Refine column and under Where click More. Then you have a nice list to browse. You might spot a map that includes your location. TIP: When you find a result, be sure to check the Related number at the top of the page so that you didn’t miss any additional pages of the map.

From Mark: Lisa and Bill, is the intro music something that you all wrote?
From Lisa and Bill: No, it’s by a talented musician named Dan Lebowitz. Our goal this year was to learn to play it ourselves 🙂 We’re glad you love it as much as we do!

National Archives Facilities Closing

by Lisa Cooke | Mar 17, 2014 | 01 What's New, Libraries, NARA

National Archives (US) facilities are closing or restructuring in three locations. But steps are being taken to maintain access (local or online) to the

National Archives, Washington, D.C. Wikimedia Commons Image by Edbrown05.

treasure trove of research materials at these facilities.

A recent press release states, “As part of ongoing budget adjustments, Archivist of the United States David S. Ferriero announced the permanent closure of three National Archives facilities. This year, the National Archives facility in Anchorage, AK, will close and two facilities in the Philadelphia, PA, area will be consolidated to a single site. Within the next two years, two Archives’ facilities in Fort Worth, TX, also will be consolidated to a single site. These closures and consolidations will result in estimated annual cost savings of approximately .3 million.”

“The National Archives budget is devoted primarily to personnel and facilities, both of which are essential to our mission,” the Archivist stated. “I recognize these cuts will be painful; however, we are committed to continuing to provide the best service to our customers and best working conditions for our staff nationwide.”

Here’s the scoop on each of the affected locations:

National Archives – Anchorage, AK, facility closing:

The National Archives’ facility in Anchorage, AK, will close permanently in FY 2014. The employees who work there will be offered positions at other National Archives facilities, with the National Archives paying relocation expenses. The less than 12,000 cubic feet of archival records in Alaska will be moved to the National Archives at Seattle, WA, where the National Archives will digitize these records so that they remain available to Alaskans through the internet. In addition, we will move approximately 7,500 cubic feet of records center holdings to Seattle, WA.

National Archives – Philadelphia, PA, facility consolidation:

The National Archives currently maintains two facilities in Philadelphia—a records center and archives at Townsend Road, and a small “storefront” archival facility at 900 Market Street in the city center. These facilities are in the same commuting area, and archival records are currently moved between the two for research use. The Market Street facility will close in FY 2014, and those employees will move to Townsend Road or telework locations. The less than 5,000 cubic feet of archival records stored at Market Street will be moved to Townsend Road, where the majority of the archival records already are stored. The Townsend Road facility’s research room will be modified to better provide appropriate access to researchers, and community outreach programs will continue.

National Archives – Fort Worth, TX, facility consolidation:

The National Archives currently maintains two facilities in Fort Worth: a combined records center and archives at John Burgess Drive, and a smaller “storefront” facility at Montgomery Plaza. The National Archives will permanently close the Montgomery Plaza facility in FY 2016. All employees at the Montgomery Plaza location will move to John Burgess or telework locations. No original records are stored at Montgomery Plaza, and researchers will have continued access to archival records through the research room at John Burgess Drive.

AncestryDNA Results Improving for Jewish and Hispanic Ancestry

by Diahan Southard | Oct 24, 2014 | 01 What's New, Ancestry, DNA, Jewish

Ancestry.com has improved the ability of AncestryDNA to find good matches for Jewish, Hispanic and other ancestries that maybe weren’t so precise before. Here’s the lowdown, quoted liberally from Ancestry.com’s press release:

The problem: Predicting genetic relatives among customers of Jewish and Hispanic descent and some other groups. “In DNA matching, we are looking for pieces of DNA that appear identical between individuals,” says the release. “For genealogy research we’re interested in DNA that’s identical because we’re both descended from a recent common ancestor. We call this identical by descent (IBD). This is what helps us to make new discoveries in finding new relatives, new ancestors, and collaborating on our research.”

“However, we also find pieces of DNA that are identical for another reason. At one extreme we find pieces of DNA that are identical because it is essential for human survival. At the other, we find pieces of DNA that are identical because two people are of the same ethnicity. We call these segments identical by state (IBS) because the piece of DNA is identical for a reason other than a recent common ancestor. This, we have found, often happens in individuals of Jewish descent.”

“The challenge in DNA matching is to tease apart which segments are IBD, and which ones are IBS….Most Jewish customers find that we predict them to be related to nearly every other Jewish customer in the database….Detecting which cousin matches were real and which ones were bogus has always been a challenge for these populations.”

First step toward a solution: “By studying patterns of matches across our more than half a million AncestryDNA customers, we found that in certain places of the genome, thousands of people were being estimated to share DNA with one another–likely a hallmark of a common ethnicity. Our scientific advancements… have allowed us to effectively “pan for gold” in our matches–by throwing out matches that appear to only be IBS, and keeping those that are IBD.”

“While the problem was more pronounced in customers of Jewish and some Hispanic descents, we observed this problem across all ethnic groups. So, all customers will see increased accuracy of their DNA matches, and significantly fewer ‘false’ matches.”

AncestryDNA results with better matches found by this method “will be available in the coming months,” says the release. They plan to email existing customers when results are ready.

Free App, E-Book Celebrate Constitution Day

by Lisa Cooke | Sep 17, 2014 | 01 What's New, Apps, History, Holidays, NARA

Today the United States celebrates Constitution Day! On this date in 1787–225 years ago–delegates finalized and signed the historic document that became the U.S. Constitution.

In celebration, the National Archives Center for Legislative Archives has launched a free mobile app, e-book and even companion tools for teachers: lesson plans and teaching activities.

“Congress Creates the Bill of Rights” is described at the National Archives website, where you can download the e-book and teaching resources. The e-book is also available in iTunes and the iBookstore for iPad, iPhone, and iPod Touch. The app is available for download on iPad at the App Store.

A press release describes the app as “an interactive learning tool for tablets that lets the user experience the proposals, debates, and revisions that shaped the Bill of Rights in the First Congress. Its menu-based organization presents a historic overview, a one-stop source that includes the evolving language of each proposed amendment as it was shaped in the House and the Senate, a close-up look at essential documents, a ‘time-lapse’ display of the creation of the First Amendment, and more.

Congress Creates the Bill of Rights eBook presents a historic narrative focusing on James Madison’s leadership role in creating the Bill of Rights and effectively completing the Constitution. Starting with the crises facing the nation in the 1780s, the narrative traces the call for constitutional amendments from the state ratification conventions, and takes the reader inside Congress as the House and the Senate worked to formulate a set of amendments to send to the states.”

Did you have ancestors who were at the Constitutional Convention? Contribute what you know at the Signers of the U.S. Constitution Project at Geni.com. The goal of this project is to build “single, documented profiles” of those who signed.

Genetic Genealogy: DNA Tests Another Step Forward

by Lisa Cooke | Oct 5, 2014 | 01 What's New, Australian, DNA

Recently a group of 100 residents from Wellington, New Zealand assembled together to determine what exactly it was they had in common. Their host? Dr. Spencer Wells, Director of the National Genographic project. Their admittance fee to this party? A cheek swab.

What they learned about themselves that evening, has a direct impact on YOU, a genealogist interested in identifying your ancestors.

You see, 800 years ago the first inhabitants of New Zealand were just beginning to explore their new territory. They had arrived from the eastern islands of Polynesia and lived in relative isolation for over 500 years.

While first discovered by the Dutch in 1642, New Zealand wasn’t regularly visited by Europeans until the late 18^th century. For Spencer Wells and the National Genographic Project, sampling people of New Zealand would provide a rare opportunity to study the genetic effect of a recent collision of indigenous and outside population groups.

We can think of mixing populations like adding a tablespoon of salt to a glass of water. At first it is easy to see the two different substances co-existing in the same location. But soon the salt becomes part of the water- creating a new substance, with only a small portion of the original substances remaining. This is what happened throughout history as outside groups arrived and intermarried with indigenous populations.

The goal of population genetics as a field of study, and specifically of the National Genographic project, is to look at the modern day population (in our example the salt water), and be able to identify which ancestral populations are present (in our example, determine which parts are salt, and which parts are water. This of course, without knowing beforehand that you were dealing with salt water!).

The National Geneographic project has identified 9 ancestral regions from which they believe all modern populations descend. These nine would be like our salt, and our water. They have then described how 43 reference population groups (our salt water) are comprised of their own unique mix of these 9 groups. They can also describe the origins of your direct maternal line, and if you are male, your direct paternal line.

This information was gathered for the Wellington residents. It was determined that the original Polynesian population and a small East Asian population are certainly the minority among a predominately Western European population group. This information will help groups like the National Genographic Project to determine the possible migration patterns of other peoples and cultures.

What does this mean for genealogy? This kind of research helps fuel the admixture results (the pie charts and percentages) reported to you by a genetic genealogy testing company when you take an autosomal DNA test. It is this research that helps genetic genealogists look at your DNA and pick out the essential, ancestral elements–your salt and your water–and determine how your unique mix reveals information about the origins and migration patterns of your ancestors.
