Show Notes: If you’ve created a MyMap in Google Maps, there’s a lot more that you can do with it if you import it into Google Earth. However, exporting it out of MyMaps as a KMZ that can be used in Google Earth isn’t really obvious. The good news is that it’s not hard to do. I’ll explain how and I’ll also show you how to import the KMZ file into Google Earth.
If you have several items in your MyMaps project, make sure that each item that you want to be included in the file that you’re exporting has a checkmark next to it. Whatever is checked is activated on the map display and will be included in your exported file.
Next, in the upper left corner of Google MyMaps, you’ll see three vertically stacked dots. When we click that, you’ll get a menu that includes Download KML. KML and KMZ are file extensions that are supported by Google Earth.
You’ll also see View Map in Google Earth in this menu. If you click that the MyMaps project will open in a new web browser tab in the web version of Google Earth. You don’t want that because the web version does not have all the features that are available in the free downloadable software version of Google Earth.
Click to select Download KML. KML stands for Keyhole Markup Language. This is a geographic file. The difference between KML and KMZ is that KML is typically a single item while a KMZ is a zipped file potentially containing several items. Each placemark and data item added to your project is a single item. When you have several like in our example project, you will want to export it as a KMZ. So even though the menu says Download KML, go ahead and click it.
When you click it you’ll get a pop-up menu with two options:
Keep data up to date with network link KML (only usable online).
This will include all your data. If any of that data is coming from another source on the cloud and that source updates, your data will update in Google Earth.
Export as KML instead of KMZ. Does not support all icons. This can zip your project as a .KMZ but it might not transfer all your icons, particularly those that might be coming from another source on the cloud.
In many cases, either of these would be fine. But when in doubt, I select Keep data up to date with network link KML so that all my project data will remain current.
After you make your selection, your file will be exported to your hard drive. You can select the destination where you want it saved. It will be a KMZ file because there are multiple items that have been zipped into one package.
How to Open an Exported MyMaps KMZ File
On a PC you will see the downloaded KMZ file in the bar at the bottom of your screen. If you click the up arrow you can open the location on your hard drive where the file was saved. You can also click Open. That opens the KMZ in a program that can read it like Google Earth if it’s already installed on your computer. The easiest way to open the file is to simply double-click it. Your computer will automatically detect that you are opening a KMZ file and it will automatically launch your Google Earth software, and open and display the file in it. It may take a few extra moments to load and run because it’s trying to do two things at once, and Google Earth is a pretty robust program.
There are three panels in Google Earth:
Search (where you enter names, addresses and more to fly to locations in Google Earth),
Places (your Google Earth files and folders These are private and are not published by Google.)
and Layers (data that can be streamed from cloud sources.)
Your project file will be in the Temporary Folder of the Places Panel. Google places opened files in the Temporary folder because it doesn’t know whether you just want to look at it one time, or you want to keep it. When you want to keep a file, you will need to drag and drop it onto MyPlaces at the top of the Places panel, or into a folder you have created.
Also, Google Earth doesn’t autosave. So it’s important to save your work before you close the program. Otherwise, your file will be lost. To save your file, in the menu at the top of the screen select File > Save > Save MyPlaces.
How to Display a MyMaps File in Google Earth
There is a small arrow next to your project file in the Places panel that indicates it is a nested project folder. Click the arrow to display the contents of this zipped container. Inside is the actual MyMaps project folder or the project. Continue to click arrows to reveal the nested content. Now that you can see the individual items, you can now work with them.
To display the entire project on the screen, double-click the main project file (not one of the nested items). Click only to highlight it. Don’t click the linked title because that will only display the descriptive text you included in your original MyMaps project.
Everything that you saw in MyMaps is now in Google Earth. You can check and uncheck items within the project in the Places panel depending on what you want to be displayed on the screen.
How to Add Content to a MyMaps File in Google Earth
You can easily add additional content to your project. Click to select the project, then add content such as a Placemark. If you selected the Keep data up to date with network link KML option when you exported your file, you won’t be able to add items to the existing folders that came over from MyMaps. However, you can add individual items or new folders by selecting the top-level project.
The beauty of working with the project file in Google Earth is that you can now add content from the Layers panel, some of which was not available to you in MyMaps. You can also add additional items from the Toolbar at the top of the Google Earth screen.

(Update 2020) When genealogists take an ancestry DNA test, they are looking for more than just their ethnicity results. They are also very interested in receiving information on other people who have tested who closely genetically match them. They want to know who the closest matches are, and if those matches have family tree information that they can share.
However, with all the people testing these days, (some being genealogists and some not) the volume of matches can become overwhelming very quickly.
Are you one of those people who have way too many genetic “4th cousins or closer” among your DNA matches? Have you ever wondered “What do I do with all these matches?!” If so, keep reading. We’re going to explore some of your options, and most importantly, how to determine how genetically close your cousins really are.
Doing the DNA Math on Your Cousins
Math can provide us with a degree of certainty in genetic genealogy. Each of us has two biological parents. We have four biological grandparents, and eight great-grandparents.
However, the farther back we go the less we can rely on math.
For example, on paper you should have sixty-four 3rd great grandparents. However, many of us find that the same person occupies more than one slot on our pedigree chart. While this significantly decreases the workload for traditional genealogy, it adversely impacts your genetic genealogy. Especially when it comes to that long long list of 4th cousins you have in your match list at any of the three major DNA testing companies.
Depending on how intermarried your lines are, you may be seeing individuals on your match list that genetically look like your fourth cousins, but they are genealogically your sixth cousins – EIGHT TIMES! So how can you tell the difference?
There are two parts to that answer: one you can control, and the other you can’t.
Distinguishing DNA Matches with Genetic Tools
While your fourth cousins and your eight-time-sixth cousins may look similar genetically, there are often small clues in the genetics that can help you tell the difference. This distinction can sometimes be detected by a testing company who, through research and validation, has been able to fine-tune their algorithms to detect these subtle differences.
Your Genetic 4th Cousins
You can participate in this double checking process by using some of the genetic tools that are available to you at Family Tree DNA, or at Gedmatch.com. But since you may not be an aspiring geneticist, let’s focus on the genealogical work you can do to determine if a match is truly a fourth cousin.
Use Google Earth to Plot Your DNA Matches
A fourth cousin designation just means that you and your match are separated by between six and twelve degrees (people). So that might be five back on your chart to your common ancestor, and five down to your match, which would make you true fourth cousins. It could also be some other permutation of that.
For our example, let’s assume true fourth cousins. That means that the two of you share one of thirty-two 3rd great grandparents (16 couples). In order to find out which set, you have two genealogical identifiers: surname and location.
Therefore, the first thing you should do is make a list of the surnames and locations of those thirty-two 3X great grandparents.
Now, most of us do not know all 16 of those couples, so you are going to have some holes. Feel free to fill in those holes with surnames on subsequent generations that will carry through to this fifth generation.
A great tool to plot your own list of ancestors geographically is the free downloadable Google Earth software.
Check to see if you have the latest version of Google Earth downloaded to your desktop or laptop computer. On your desktop, look for a grey and white globe. If you see a blue and white globe, you have the older original free version of Google Earth. However, a few years ago, Google made their Google Earth Pro version free to everyone, and it is now the standard.
If you do have Google Earth Pro (the grey globe software) then you’re ready to go.

When complete click Run Google Earth
Now that you have Google Earth, you can begin by creating a folder in the Places panel in Google Earth devoted to your 16 couples. Here’s how:
1. In the Places panel, right-click on MyPlaces and select Add > Folder:
Right-click on MyPlaces > Add > Folder
2. Name the folder and then click OK:
Creating a folder in Google Earth
3. Now you will see your new DNA folder for your 16 couples in the Places panel. If you don’t see it, look toward the bottom of the list. You can move the folder to any location within the list by dragging and dropping it.
Create a folder in Google Earth for DNA 16 couples
Once you have your DNA folder created fro your 16 couples, you can then easily plot your surnames and locations.
How to Plot Your Surnames and Locations in Google Earth:
1. Click your new DNA folder to select it. This will ensure that the placemark you are about to create will be stored in that folder.
2. In the search box (upper left corner of the Google Earth software) type in the first location and click Search. Google Earth will fly to that location on the map.
Type the locaton in the Search box and click Search.
3. In the toolbar along the top of the screen, click the placemark button to place a pushpin in that location:
Click the Placemark button in the Google Earth toolbar.
4. In the Placemark dialogue box, enter a title for hte pushpin placemark. Click the OK button to close the box and set your placemark.
5. Repeat the process for all the locations.
Then evaluate the fifth generation of your fourth cousin matches for genealogical information that lines up with any of the items on your list.
You can also plot the surnames and locations of your matches in Google Earth. This is where Google Earth really comes in handy. The free software makes it very easy to see when your ancestral home may be bordering the locations of your matches. Those with whom you find a similarity become your best matches, and your best chance of determining your connection. Those without an obvious connection cycle to the bottom of your pile for a genetic evaluation. You can perform these same kinds of searches for your second and third cousins as well.
As you begin to become more familiar with the fifth generations of your matches, you may also start to see patterns of surnames or locations emerge among your matches. These then become the surnames and locations that might be able to fill the missing spaces in your pedigree chart.

How can you keep up with new online information on your family history that may appear at any moment? You can’t, unless you run constant searches on your web browser, and who’s got time for that? Google does! And it accomplish that incredible search feat for you through Google Alerts.
Google Alerts is like having your own virtual research assistant! When you key in your favorite searches, Google Alerts will automatically email you when there are new Google results for your search terms.
2. Sign in to your Google account (or create one).
3. The first time you create an alert, click where it says, “You don’t have any Google Alerts. Try creating one.” Fill in the screen that pops up:
4. Type in your search query. In the example above, I’ve entered my specific search: “Larson” “Winthrop” Minnesota.
5. Make selections to further refine your search alert:
The type of content you’re looking for: news, blogs, videos, discussions, books or everything.
How often you want to receive the alerts by email.
The type of results you want to get. You may want to receive all results, not just the best results which will give you an opportunity to see how your search does. You can always change settings later.
6. Enter the email address where you want the alert emails to be delivered. Google will alert you to new content when it is posted on the Web.
